Her
      child disturbs her when she prays
Question

                I always try to perform
      my Solat on time. However I have an 18 month old baby and there are times
      when there is no other adult to watch him when I do my solat. The problem
      is whenever I do my solat with him close by, he will sit in front of me
      and basically disturb my solat. My question is, Is my solat unacceptable
      when he does this, and also, is it better to delay my solat even if it
      means missing it and doing qada'?
Praise be to Allah., the Lord of the Worlds, and
    blessings be upon our Prophet Muhammad and all his family and companions.
    The Muslim has to perform the prayers at the appointed
    times and it is not permissible to delay them for no reason, because Allaah
    says (interpretation of the meaning):
“Verily, Al-Salaat (the prayer) is enjoined on the
    believers at fixed hours” [al-Nisaa’ 4:103], i.e. it is obligatory
    at specific times, and should not be brought forward or delayed. The timing
    is the most important condition of prayer: if a person is not able to fulfil
    some of the conditions of the prayer, he should still pray as best as he
    can, within the prescribed time, and he should not delay it. One of the
    things that indicate the importance of the times of prayer in sharee’ah is
    the fact that if a Muslim cannot find water, he should do tayammum
    (“dry ablution” using earth or sand) and pray, even if he is sure that
    he will find water after the time for that prayer has passed.
The fact that a child walks in front of his mother whilst
    she is praying does not have any effect on the prayer and does not make it
    invalid. It was reported that the Prophet 
 (peace and blessings of
    Allaah be upon him) carried a small girl whilst he was praying, picking her
    up when he stood up and putting her down when he prostrated (sujood). This
    was reported by al-Bukhaari and Muslim from Abu Qutaadah al-Ansaari: “The
    Messenger of Allaah 
 (peace and blessings of Allaah be upon him) used to
    pray whilst he was carrying Umaamah, the daughter of Zaynab bint
    Rasool-Allaah 
 (peace and blessings of Allaah be upon him). According to
    the report of Abu’l-‘Aas ibn Rabee’ah ibn ‘Abd Shams, when he
    prostrated he put her down, and when he stood up he picked her up.” (Narrated
    by al-Bukhaari, no. 486, and Muslim, no. 844).
    
    It was also reported that he 
 (peace and blessings of
    Allaah be upon him) allowed a small boy to ride on his shoulders and he
    still completed the prayer. This was reported by ‘Abd-Allaah ibn Shaddaad
    from his father: “The Messenger of Allaah 
 (peace and blessings of
    Allaah be upon him) came out to lead us in either Maghrib or ‘Ishaa’ one
    night, and he was carrying Hasan or Husayn. The Messenger of Allaah 
    (peace and blessings of Allaah be upon him) came forward and put (the child)
    down, then he said Takbeer and started to pray. During the prayer, he
    prostrated and made his prostration long. My father said: ‘I raised my
    head and I saw the child on the back of the Messenger of Allaah 
 (peace
    and blessings of Allaah be upon him) whilst he was prostrating, so I
    returned to my prostration.’ When the Messenger of Allaah 
 (peace and
    blessings of Allaah be upon him) finished praying, the people said, ‘O
    Messenger of Allaah, during your prayer you prostrated for so long that we
    thought something had happened or that you were receiving Revelation.’ He
    said, ‘Nothing at all happened, but my son was riding on my back and I did
    not want to disturb him until he had had enough.’” (Narrated by
    al-Nisaa’i, no. 1192; classed as saheeh by al-Albaani – may Allaah have
    mercy on him – in Saheeh Sunan al-Nisaa’i, 1/246).
    
    If you pick you child up and put him down whilst you are
    praying, it will not do any harm. Keep offering your prayers at the
    appointed times. May Allaah help us and you to do all that is good.
