Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings of Allah be upon him) entered into the state of Ihram immediately after the prayer.

It is narrated from Hasan that the Noble Prophet (peace and blessings be upon him) entered into the state of Ihram after the Zuhr prayer, and Hasan also preferred to enter into Ihram after the Zuhr prayer. And if a person is unable to enter into Ihram after the Zuhr prayer, he may do so after the Asr prayer.

Hazrat Ibn Sabit says that your righteous predecessors liked to recite the Talbiyah in four situations: after prayer, when descending into a valley or ascending from a valley, and when joining a group of companions.

Ibrahim says that it is recommended to recite the Talbiyah at certain places and occasions: after the obligatory prayer, when you ascend to a height, when you descend into a valley, whenever your camel is standing beside you and you are about to mount it, and whenever you meet your group.

Hazrat Aswad used to enter into the state of Ihram after the obligatory prayer.

Hazrat Khaythamah states that the Companions considered it preferable to recite the Talbiyah on six occasions: after prayer, when mounting a ride, when ascending to a high place, when descending into a valley, and when some of them met others.

Hazrat Abdul Malik says that I asked Hazrat Ata when should a person recite the Talbiyah if he intends to enter into Ihram? He replied: If he wishes, after the obligatory prayer, and if he wishes, when his mount is brought, and when he is about to mount, he should begin and say: { سُبْحٰنَ الَّذِیْ سَخَّرَ لَنَا ہٰذَا وَمَا کُنَّا لَہٗ مُقْرِنِیْنَ }.

Hazrat Qasim used to recite the Talbiyah after every prayer, whether it was obligatory or voluntary.
