Hadith 5079
Al-Harith bin Muslim al-Tamimi quoted his father Muslim bin al-Harith al-Tamimi as saying that the Messenger of Allah ﷺ told him secretly: When you finish the sunset prayer, say: 'O Allah, protect me from Hell" seven times; for if you say that and die that night, protection from it would be recorded for you; and when you finish the dawn prayer, say it in a similar way, for if you die that day, protection from it would be recorded for you. Abu Saeed told me that al-Harith said: The Messenger of Allah ﷺ said this to us secretly, so we confine it to our brethren.
Hadith 5080
Narrated Muslim ibn al-Harith ibn Muslim at-Tamimi: A similar tradition (to No. 5061) has been transmitted by Muslim ibn al-Harith ibn Muslim at-Tamimi on the authority of his father from the Prophet ﷺ through a different chain of narrators, up to "protection from it". But this version says: "before speaking to anyone". In this version Ali ibn Sahl said that his father told him. Ali and Ibn al-Musaffa said: The Messenger of Allah ﷺ sent us on an expedition. When we reached the place of attack, I galloped my horse and outstripped my companions, and the people of that locality received me with a great noise. I said to them: Say "There is no god but Allah, " and you will be protected. They said this. My companions blamed me, saying: You deprived us of the booty. When we came to the Messenger of Allah ﷺ, they told him what I had done. So he called me, appreciating what I had done, and said: Allah has recorded for you so and so (a reward) for every man of them. Abdur Rahman said: I forgot the reward. The Messenger of Allah ﷺ then said: I shall write a will for you after me. He did this and stamped it, and gave it to me, saying. . . . He then mentioned the rest of the tradition to the same effect. Ibn al-Musaffa said: I heard al-Harith ibn Muslim ibn al-Harith at-Tamimi transmitting it from his father.
