Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When a man is praying and permission is sought from him, he should grant permission by saying «سبحان الله», and when a woman is praying and permission is sought from her, she should grant permission by clapping."

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) used to pray, and when he would go into prostration, Hasan and Husayn would jump and climb onto his back. When the companions intended to stop them, he (peace and blessings be upon him) would gesture to let them (remain as they were). When he completed the prayer, he would seat them in his lap and say: "Whoever loves me should love these two."

It is narrated from Sayyiduna Abdullah bin Zaid and Sayyiduna Abu Basheer Ansari (may Allah be pleased with them) that the Messenger of Allah (peace and blessings be upon him) was leading the companions in prayer one day in the valley of Batha. A woman wanted to pass in front, so the Prophet (peace and blessings be upon him) gestured to her to stop. Thus, she stepped back. When the Prophet (peace and blessings be upon him) finished the prayer, she passed in front.
