And the evidence that one tasleem is sufficient, and this is from the differences in what is permissible, so the one who is praying has the choice between giving one tasleem or giving two tasleems, as is the view of the people of Hijaz.

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Prophet Muhammad (peace and blessings be upon him), while in prayer, would incline slightly to his right side and turn his face (i.e., forward) to give the greeting of peace (salaam).

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that she would say one salam while saying «‏‏‏‏السَّلَامُ عَلَيْكُمْ» ‏‏‏‏ in front of her face.

Hazrat Hisham bin Urwah narrates from his father Sayyiduna Urwah (may Allah be pleased with him) that he «‏‏‏‏السَّلَامُ عَلَيْكُمْ» ‏‏‏‏ used to say salam only once.

Hazrat Qasim (may Allah have mercy on him) narrates that I saw Sayyida Aisha (may Allah be pleased with her) turning her head once for salam. Imam Abu Bakr (may Allah have mercy on him), through the chain of his respected teacher Janab Bundar, narrates from Sayyiduna Ubaidullah (may Allah be pleased with him) a similar narration, and in it, he adds that she (Sayyida Aisha, may Allah be pleased with her) did not turn to the right or left when saying salam.
