It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Bilal gives the call to prayer at night, so after his call to prayer, you may continue eating and drinking. When Ibn Umm Maktum gives the call to prayer, then stop eating and drinking.

It is narrated from Hazrat Abdullah that the Messenger of Allah, peace and blessings be upon him, said: Let not Bilal’s call to prayer prevent you from eating the pre-dawn meal (suhoor), for he gives the call to prayer during the night so that the one who is sleeping may wake up and the one who is standing in prayer during the night may return.

Hazrat Aisha (may Allah be pleased with her) narrates that Hazrat Bilal used to give the call to prayer at night. Upon this, the Messenger of Allah (peace and blessings be upon him) said that continue eating and drinking until Ibn Umm Maktum gives the call to prayer.

9171 - (W) (1) From al-Qasim ibn Muhammad, from Aisha, that Bilal used to call the adhan at night, so the Messenger of Allah صلی اللہ علیہ وسلم said: "Eat and drink until Ibn Umm Maktum calls the adhan." (2).

It is narrated from Hazrat Anas that the Messenger of Allah, peace and blessings be upon him, said: "Do not let Bilal's call to prayer prevent you from taking suhoor, because his eyesight is weak."

It is narrated from Hazrat Samurah bin Jundub that the Messenger of Allah, peace and blessings be upon him, said: "Do not let Bilal's call to prayer or the vertically spreading dawn prevent you from taking suhoor; however, when the dawn appears across the horizon in width, then stop eating and drinking."

Hazrat Zaid bin Thabit narrates that we ate sahur with the Messenger of Allah, peace and blessings be upon him, then we stood up for prayer. He was asked, "How much time was there between sahur and the prayer?" He replied, "About the time it takes to recite fifty verses."

Hazrat Salim bin Ubaid Ashja'i narrates that once I was with Hazrat Abu Bakr. He said to me to be mindful of the morning. Then he partook in the pre-dawn meal (Sahri).

Hazrat Abu Aqil narrates that I ate sahur with Hazrat Ali (may Allah be pleased with him). After eating sahur, he instructed his muezzin to give the call to prayer (adhan).

Hazrat Amir bin Matar says that I came to the house of Hazrat Abdullah, he placed before us the leftover food from his sahri. We had sahri with him, then the prayer was established and we went and offered the prayer with him.
