Sayyiduna Abdullah bin Umar (may Allah be pleased with him) narrates from Sayyida Hafsa (may Allah be pleased with her) that when the muezzin would call the adhan, the Prophet (peace and blessings be upon him) would perform two rak‘ahs and make food forbidden (for the fasting person), and the adhan would not be given until true dawn had appeared.

It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The adhan of Bilal (may Allah be pleased with him) and the false dawn should not prevent you from eating suhoor; but when the spreading light appears on the horizon, that is, the true dawn, then stop eating.

(Second chain) The Messenger of Allah, peace and blessings be upon him, said: Let not the adhan of Bilal, may Allah be pleased with him, nor this (false dawn) whiteness cause you any doubt or confusion; rather, when the true dawn breaks or appears (then the time for suhoor ends).

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Do not let Bilal’s (may Allah be pleased with him) adhan prevent you from taking suhoor, because his eyesight is somewhat impaired.

Sayyiduna Abdullah bin Umar (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Bilal (may Allah be pleased with him) gives the call to prayer at night, so keep eating and drinking until Ibn Umm Maktum (may Allah be pleased with him) gives the call to prayer.

It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: Indeed, Bilal (may Allah be pleased with him) calls the adhan at night, so you may continue eating and drinking until Ibn Umm Maktum (may Allah be pleased with him) calls the adhan. Sayyida (Aisha) says: To my knowledge, (the interval between these two adhans was such that) when one would descend after calling the adhan, the other would ascend to call the adhan.

Khubaib says: I heard from my paternal aunt (Sayyida Anisah, may Allah be pleased with her), who had also performed Hajj with the Prophet Muhammad (peace and blessings be upon him), that she said: The Messenger of Allah (peace and blessings be upon him) said: Ibn Umm Maktum (may Allah be pleased with him) gives the call to prayer at night, so you may continue eating and drinking until Bilal (may Allah be pleased with him) gives the call to prayer. Or the Prophet (peace and blessings be upon him) said: Bilal (may Allah be pleased with him) gives the call to prayer at night, so you may continue eating and drinking until Ibn Umm Maktum (may Allah be pleased with him) gives the call to prayer. (There was only a slight interval between the two calls to prayer; as soon as one would come down after giving the call, the other would ascend to give it. Sometimes, we would cling to the second muezzin and say: Wait a little so that we may finish our pre-dawn meal.)

(Second chain) Khubaib narrates from his paternal aunt Sayyida Anisah bint Khubaib (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: When Ibn Umm Maktum (may Allah be pleased with him) gives the call to prayer, continue eating and drinking, but when Bilal (may Allah be pleased with him) gives the call to prayer, then stop eating and drinking. Sayyida Anisah (may Allah be pleased with her) says: When any woman still had her pre-dawn meal remaining, she would say to Sayyiduna Bilal (may Allah be pleased with him): Wait a little, so that I may finish my pre-dawn meal.

Narrated by Sayyiduna Anas bin Malik (may Allah be pleased with him): The Messenger of Allah (may Allah bless him and grant him peace) and Sayyiduna Zaid bin Thabit (may Allah be pleased with him) took suhoor, and when they finished suhoor, the Messenger of Allah (peace and blessings be upon him) stood up for prayer. Qatadah says: We asked Sayyiduna Anas (may Allah be pleased with him): What was the interval between their finishing suhoor and starting the prayer? He said: The interval was as long as it takes a man to recite fifty verses.

Sayyiduna Anas (may Allah be pleased with him) narrates from Sayyiduna Zaid bin Thabit (may Allah be pleased with him), who says: We took suhoor with the Messenger of Allah (peace and blessings be upon him), after which we went to the mosque and the iqamah for prayer was given there. I asked Sayyiduna Zaid (may Allah be pleased with him): How much time was there between these two actions? He said: As much as it takes a man to recite fifty verses.
