3 – Standing for the prayer. Al-Bukhārī (637) and Muslim (604) relate: “When the iqāmah is pronounced for the prayer, do not rise until you see me.”
4 – As for the muqim actually beginning the iqāmah, Muslim records from Jābir b. Samurah (606): “Bilāl would not give the iqāmah until the Messenger of Allah ﷺ had come out.”
5 – The outward sense of the first report is that the muqim may begin even if the Prophet ﷺ has not yet appeared, while the second seems to require that he delay until the Prophet has left his house and become visible. The scholars harmonised the two by saying that Bilāl would watch for the Prophet’s emergence; once he saw him, he would start the iqāmah before most people had noticed him, and when they then caught sight of the Prophet they would rise for the prayer.
Scholarly disagreement
Al-Mughnī states: It is recommended for the congregant to stand when the muʾadhdhin says, “qad qāmat al-ṣalāh” (the prayer has commenced).
Ibn al-Mundhir said: The people of the Two Sanctuaries are unanimously agreed on this.
Al-Shāfiʿī said: He should stand when the muʾadhdhin has finished the iqāmah.
Abū Ḥanīfah said: He stands when the muʾadhdhin says, “ḥayya ʿala al-ṣalāh” (come to the prayer).
According to us—the Ḥanbalis—the imam should not pronounce the opening takbīr until the muqim has completed the iqāmah, and this is the practice of most imams throughout the lands. What is reported from Imām Abū Ḥanīfah—that he begins the takbīr when the muqim says, “qad qāmat al-ṣalāh”—is not the authenticated position in his school; the sound, fatwā-level view among them agrees with the majority.
Mālik said in the Muwaṭṭaʾ: I have not heard any fixed rule about when the people should rise once the prayer is being established; in my opinion it depends on their ability, for some are agile while others are slower.
The earlier hadith of Abū Qatādah, “When the iqāmah is pronounced for the prayer, do not rise until you see me,” likewise shows that the people’s rising is tied to seeing the imam coming forward to lead the prayer.
