Farwah bin Nawfal (ra) narrated that: He came to the Prophet ( صلی اللہ علیہ وسلم ) and said:“O Messenger of Allah, teach me something that I may say when I go to my bed.”So he said:“Recite: Say: ‘O you disbelievers’ for verily it is a disavowal of Shirk.”Shu`bah said:“Sometimes he would say: ‘One time’ and sometime he would not say it.”(Another chain) from Farwah bin Nawfal, from his father: "That he came to the Prophet ( صلی اللہ علیہ وسلم )" then he mentioned similar in meaning. And this is more correct. [Abu `Eisa said:] And Zubair reported this hadith from Ishaq, from Farwah bin Nawfal, from his father from the Prophet ( صلی اللہ علیہ وسلم ), with similar wording. This is more appropriate and more correct than the narration of Shu`bah. The companions of Abu Ishaq were confused in the narration of this hadith. This hadith has been reported through routes other than this. `Abdur-Rahman is the brother of Farwah bin Nawfal.

Jabir said:`“The Prophet would not sleep until he reached Tanzil as-Sajdah and Tabarak.”

`A'isha (ra) said:`“The Prophet ( صلی اللہ علیہ وسلم ) would not sleep until he recited Az-Zumar and Banu Isra’il.”Muhammad bin Ismail informed me:“This Abu Lubabah’s (a narrator in the chain) name is Marwan, the freed slave of Abdur-Rahman bin Ziyad. He heard from Aisha, and Hammad bin Zaid heard from him.”

Ar-Irbad bin Sariyah (ra) narrated that: The Prophet ( صلی اللہ علیہ وسلم ) would not sleep until he had recited Al-Musabbihat, and he would say:“In them is an Ayah that is better than a thousand Ayah.”
