Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "None of you should be prevented from (eating) sahur by Bilal’s (may Allah be pleased with him) call to prayer, because he gives the adhan at night so that the one among you who is praying tahajjud may return (for rest), and so that the one who is sleeping may wake up. And it is not that anyone should say that morning (has come)." And the Prophet (peace be upon him) gestured with his fingers, raising them upwards and then lowering them down, until (he showed) like this (i.e., when the whiteness spreads). (The narrator Zuhair) placed his two index fingers one over the other, then spread them to his right and left (i.e., when the whiteness spreads in all directions), then understand that morning has come.

In another narration, it is stated that the Noble Prophet (peace and blessings of Allah be upon him) said: "Between every two calls to prayer (i.e., the adhan and the iqamah) there is a prayer, between every two calls to prayer (i.e., the adhan and the iqamah) there is a prayer." Then, the third time, he said: "If anyone wishes (he may offer it)."

Sayyiduna Malik bin Huwairith (may Allah be pleased with him) says: We came to the Prophet Muhammad (peace and blessings of Allah be upon him) and stayed in his company for twenty nights and days, and the Messenger of Allah (peace and blessings of Allah be upon him) was gentle-hearted and kind. When he (peace and blessings of Allah be upon him) realized that we were longing to return to our families, he (peace and blessings of Allah be upon him) said: "Return and stay among your people, teach them, command them (to do good), and establish prayer. When the time for prayer comes, let one of you give the call to prayer (adhan), and let the eldest among you lead the prayer."

Sayyiduna Malik bin Huwairith (may Allah be pleased with him) says that two persons came to the Prophet (peace and blessings of Allah be upon him) with the intention of traveling, so the Prophet (peace and blessings of Allah be upon him) said to them: "When you set out (and the time for prayer comes), then give the adhan, then say the iqamah, and after that, the elder among you should lead you in prayer."

Narrated by Sayyiduna Ibn Umar (may Allah be pleased with them both): The Messenger of Allah (peace and blessings of Allah be upon him) used to instruct the mu’adhdhin, after the adhan, to say: "Pray in your places" (and do not come for the congregation), and this was done on cold or rainy nights (when) on a journey.

‘Sayyiduna Abu Qatadah (may Allah be pleased with him) says that while we were praying with the Prophet (peace and blessings of Allah be upon him), he heard the voices of some people. When the Prophet (peace and blessings of Allah be upon him) finished the prayer, he said:“What is the matter with you? (i.e., why was there this commotion?)”They replied that they had hurried for the prayer. The Prophet (peace and blessings of Allah be upon him) said:“Do not do so. When you come for the prayer, come with calmness and tranquility. Then whatever part of the prayer you catch, perform it, and whatever you miss, complete it.”

Narrated Abu Huraira (may Allah be pleased with him): (On one occasion) the Messenger of Allah (peace and blessings of Allah be upon him) said: "By Him in Whose Hand is my soul, I have indeed intended to order that firewood be collected, then order for the call to prayer to be given for the prayer, then appoint a man to lead the people in prayer, and I would go to some people and burn their houses over them. By Him in Whose Hand is my soul, if any one of them knew that he would find a fat bone or two good pieces of meat, he would surely come to the 'Isha prayer."
