Sending blessings upon the Prophet (peace and blessings of Allaah be upon him) after the iqaamah
Question

                Is it permissible to read ‘as-salaah al-ibraheemiyyah’ and send blessings on the prophet, peace be upon him, after iqamah is called? Is this an occasion of sending blessings on the prophet, peace be upon him? Did Ibn Al-Qayyim mention this time when he mentioned the timings of sending blessings on our beloved prophet, peace be upon him?.
Praise be to Allah.
    The majority of scholars are of the view that it is mustahabb 
    to send blessings upon the Prophet  (peace and blessings of Allaah be 
    upon him) after the iqaamah, as after the adhaan, and that it is mustahabb 
    to repeat after the one who saying the iqaamah, then to say the du’aa’: 
    Allahumma Rabba hadhihi’l-da’wah… (O Allaah, Lord of this call …) 

    This is the view of the majority of Hanafis, and is the view 
    of the Shaafa’is and Hanbalis. Among contemporary scholars, it is the view 
    of the scholars of the Standing Committee for Issuing Fatwas; Shaykh ‘Abd 
    al-‘Azeez ibn Baaz; and Shaykh al-Albaani (may Allaah have mercy on him). 

    Ibn al-Qayyim (may Allaah have mercy on him) mentioned this 
    (i.e., after the iqaamah) as being one of the situations in which blessings 
    should be sent upon the Prophet  (peace and blessings of Allaah be upon 
    him), in his book Jala’ al-Afhaam fi Fadl al-Salaati wa’l-Salaami ‘ala 
    Khayr al-Anaam (p. 441-445). 

    Some of the Hanafis are of the view that repeating after the 
    muezzin then sending blessings upon the Prophet  (peace and blessings of 
    Allaah be upon him) and saying this du’aa’ applies only to the adhaan, and 
    it is not mustahabb to do that in the case of the iqaamah. Among 
    contemporary scholars, this view was favoured by Shaykh Muhammad ibn 
    ‘Uthaymeen (may Allaah have mercy on him). 

    This has been discussed in the answer to question no. 
    111791. 
    This is one of the matters that are subject to ijtihaad. We favour the view 
    that repeating after the muezzin, then sending blessings upon the Prophet 
     (peace and blessings of Allaah be upon him) then saying the du’aa “Allaahumma 
    Rabba hadhihi’l-da’wat il-taammah…” applies only to the adhaan. 

    And Allaah knows best.
