Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) entered the mosque of Banu Amr bin Awf, Quba, and prayed there. Some men from among the Ansar entered upon him and greeted him with salam. Sayyiduna Suhaib (may Allah be pleased with him) was also with the Prophet (peace and blessings be upon him). I asked Sayyiduna Suhaib (may Allah be pleased with him): When salam was said to the Prophet (peace and blessings be upon him) during prayer, what would he do? He replied: He would gesture with his hand. Sufyan says: I said to a man: Ask Zaid, have you heard from Abdullah bin Wahb? I said: I will ask him. He said: O Abu Usamah! Have you heard from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both)? He said: I have seen him and spoken to him.

Sayyiduna Abdullah bin Umar, may Allah be pleased with them, narrates that the Companion of the Messenger, Sayyiduna Suhaib, may Allah be pleased with him, said: I passed by the Noble Prophet, peace and blessings be upon him, while he was praying. I greeted him with salam, and he, peace and blessings be upon him, responded to me by gesturing. The narrator says: I think he mentioned that he gestured with his finger.

It is narrated from Sayyiduna Ammar bin Yasir, may Allah be pleased with him, that he said: I came to the Noble Prophet, peace and blessings be upon him, while he was performing prayer. I greeted him with salam, and he, peace and blessings be upon him, replied to my salam.

It is narrated from Sayyiduna Ibn Jabir (may Allah be pleased with him), he says: I went to the Noble Prophet (peace and blessings be upon him) while he (peace and blessings be upon him) was urinating. I said: "Peace be upon you, O Messenger of Allah!" but he (peace and blessings be upon him) did not reply. I said again: "Peace be upon you, O Messenger of Allah!" but he (peace and blessings be upon him) did not reply. I said again: "Peace be upon you, O Messenger of Allah!" but he (peace and blessings be upon him) did not reply. Then the Noble Prophet (peace and blessings be upon him) walked away, and I followed behind him. He (peace and blessings be upon him) entered his house, and I entered the mosque and sat there in sadness. Meanwhile, the Noble Prophet (peace and blessings be upon him) came to me after he (peace and blessings be upon him) had purified himself. Then he (peace and blessings be upon him) replied to all three greetings, saying: "Peace be upon you and the mercy of Allah," "Peace be upon you and the mercy of Allah," and "Peace be upon you and the mercy of Allah." Then he (peace and blessings be upon him) said: "O Abdullah! Shall I tell you the best Surah of the Holy Qur'an?" I said: "Yes, of course, do tell me, O Messenger of Allah!" He (peace and blessings be upon him) said: "Recite 'All praise is due to Allah, Lord of the worlds' until you complete it."
