He prays and fasts and prays qiyaam, but he mistreats his wife and neighbours
Question

                A person (man) prays in the mosque, prays qiyam al layl, fasts on Monday, Thursday and the 13, 14,15 of each month. But he has no achlaaq with: his wife (there is every day quarrel at home), neighbors, relatives of the wife, friend of his wife, other people. What can you say about such person?.
Praise be to Allah.
    Good morals are one of the greatest purposes which the 
    Prophet  (peace and blessings of Allaah be upon him) was sent to promote 
    among people. Allaah sent him to establish the religion of truth and a life 
    of fairness and justice among people, after Allaah looked at the people of 
    this earth and disapproved of them and hated what they were following of 
    shirk, ignorance and bad morals, except for the remnants of the People of 
    the Book. 

    The Prophet  (peace and blessings of Allaah be upon him) 
    expressed this great aim, which was one of the aims of his mission, when he 
    said “I have only been sent …” to give the impression that all beliefs and 
    rulings of Islam are only aimed at achieving that purpose, which is to 
    establish good morals and justice and kindness. 

    He  (peace and blessings of Allaah be upon him) said: “I 
    have only been sent to complete good morals.” 

    Narrated by Ahmad in al-Musnad (2/318) and classed as 
    hasan by al-Albaani in al-Silsilah al-Saheehah (no. 45). 

    Undoubtedly one of the greatest problems that some Muslims 
    are suffering from today is the split between worship and morals, whereby 
    the physical practice of acts of worship – in some people – has become like 
    customs or rituals, in which the outward motions are done without any 
    attention to their effect on the heart and soul, even though the four 
    pillars of Islam – which are the most important acts of worship – are aimed 
    at disciplining the soul and improving morals. 

    For example, concerning prayer Allaah says (interpretation of 
    the meaning): 

    “Recite (O Muhammad صلى الله 
    عليه وسلم) what has been revealed to you of the Book (the Qur’aan), 
    and perform As‑Salaah (Iqamat‑as‑Salaah). Verily, As‑Salaah (the prayer) 
    prevents from Al‑Fahshaa’ (i.e. great sins of every kind, unlawful sexual 
    intercourse) and Al‑Munkar (i.e. disbelief, polytheism, and every kind of 
    evil wicked deed) and the remembering(praising) of (you 
    by) Allaah (in front of the angels) is greater indeed [than your remembering 
    (praising) of Allaah in prayers]. And Allaah knows what you do”

    [al-‘Ankaboot 29:45]

    It was narrated that Abu Hurayrah (may Allaah be pleased with 
    him) said: A man said: O Messenger of Allaah, “So and so (a woman) – and he 
    spoke of how much she prayed and fasted and gave charity – but she annoys 
    her neighbours with her (sharp) tongue.” He said: “She will be in Hell.”

    He said: “O Messenger of Allaah, So and so (another woman) – 
    and he spoke of how little she fasted and gave charity and prayed – but she 
    gives cheese in charity and she does not annoy her neighbours with her 
    (sharp) tongue.” He said: “She will be in Paradise.” 

    Narrated by Ahmad in al-Musnad (2/440) and classed as 
    saheeh by al-Albaani in al-Targheeb wa’l-Tarheeb (3/321) and by 
    Shaykh al-Albaani in al-Silsilah al-Saheehah (no. 190). 

    The same applies to the duty of fasting; the Prophet  
    (peace and blessings of Allaah be upon him) stated that a good attitude is 
    the reward of an accepted fast, and that if a person does not find this 
    benefit, then his fast will not benefit him at all before Allaah. 

    It was narrated from Abu Hurayrah (may Allaah be pleased with 
    him) that the Messenger of Allaah  (peace and blessings of Allaah be 
    upon him) said: “Whoever does not give up false speech and acting upon it, 
    Allaah has no need of his giving up his food and drink.” Narrated by 
    al-Bukhaari (1903). Zakaah is also prescribed to purify the soul, and 
    cleanse it of the stain of sin and spiritual maladies. Allaah says 
    (interpretation of the meaning):

    “Take Sadaqah (alms) from their wealth in order to purify 
    them and sanctify them with it”

    [al-Tawbah 9:103]. 

    The same applies to the fifth pillar of Islam, namely Hajj. 
    Allaah says (interpretation of the meaning): 

    “The Hajj (pilgrimage) is (in) the well-known (lunar year) 
    months (i.e. the 10th month, the 11th month and the first ten days of the 
    12th month of the Islamic calendar, i.e. two months and ten days). So 
    whosoever intends to perform Hajj therein (by assuming Ihraam), then he 
    should not have sexual relations (with his wife), nor commit sin, nor 
    dispute unjustly during the Hajj”

    [al-Baqarah 2:197]. 

    If we were to discuss the great importance of good morals in 
    Islam. Quoting from the Qur'aan and Sunnah, it would take far too long. Ibn 
    al-Qayyim (may Allaah have mercy on him) included a chapter in Madaarij 
    al-Saalikeen (2/307) which he entitled The religion is all morals; 
    whoever has better morals than you is more committed to the religion than 
    you. 

    But it is sufficient for us to ponder how good morals are 
    among the basic aims behind the prescription of the pillars of Islam. This 
    is indicative of the sublime status of this aim, and the importance of 
    adhering to it, and making it a priority for every Muslim who believes in 
    the Oneness of Allaah (Tawheed). 

    What you have to do is to remind that person who is 
    mistreating his wife and neighbours to fear Allaah, and tell him that Allaah 
    does not approve of these actions of his, rather He is angered by his 
    annoying his neighbour, wife and relatives. Where are the effects of qiyaam 
    and prayer on his heart, attitude and actions? 

    But they should be kind towards him when advising him, 
    because his keenness for worship is a sign of goodness, in sha Allaah. Imam 
    Ahmad narrated in al-Musnad that Abu Hurayrah (may Allaah be pleased 
    with him) said: A man came to the Prophet  (peace and blessings of 
    Allaah be upon him) and said: So and so prays at night, but in the morning 
    he steals. He said: He will what you mention concerning him will make him 
    give up.  

    Al-Bayhaqi said in Majma’ al-Zawaa’id (2/261): The men 
    of its isnaad are thiqaat (trustworthy). Shu’ayb al-Arna’oot and ‘Aadil 
    Murshid said in Tahqeeq al-Musnad (15/483): its isnaad is saheeh and 
    its men are thiqaat, the men of the two Shaykhs (al-Bukhaari and Muslim). 

    And Allaah knows best.
