37:35As-Saaffaat

They (the Companions) accompanied the Prophet (ﷺ) while they were climbing the turning of a hill. A man uttered loudly: "There is no god but Allah, and Allah is most great" when he ascended the hill. The Prophet of Allah (ﷺ) said: You are not supplicating one who is deaf or absent. He then said: 'Abd Allah b. Qais. The narrator then transmitted the tradition to the same effect.

"Abu Talib fell ill, so the Quraish went to see him, and the Prophet (ﷺ) went to see him. There was a gathering there with Abu Talib, so Abu Jahl stood up enraged, to prevent him (the Prophet (ﷺ) from entering)." He said: "He complained to Abu Talib. So he (Abu Talib) said: 'O my nephew! What is it that you want from your people?' He said: 'I only want one word from them, for which, if they were to say it, then the Arabs will become their followers, and the non-Arabs will pay Jizyah to them.' He said: 'One word?' He replied: 'One word.' So he said: 'O uncle! Let them say La Ilaha Illallah' so they replied: 'One God? We have not heard (the like) of this in the religion of these later days. This is nothing but an invention.'" He said: "So the (following) was revealed in the Qur'an about them: 'Sad. By the Qur'an full of reminding. Those who disbelieve are in false pride and opposition...' up to His saying: 'We have not heard (the like) of this in the religion of these later days. This is nothing but an invention (38:1-7).'"

"Some of my companions told me that Hisham had said, "When the Mu'adh-dhin said, "Haiyi `alassala (come for the prayer)." Muawiya said, "La hawla wala quwata illa billah (There is neither might nor any power except with Allah)" and added, "We heard your Prophet saying the same."

(and he was not a liar) When Allah's Messenger (ﷺ) said, "Sami`a l-lahu liman hamidah" none of us bent his back (for prostration) till the Prophet (ﷺ) prostrated and then we would prostrate after him.
