Ayoub al-Sakhtiyani أيوب السختياني · The Book on Jihad

From one who heard the Prophet (ﷺ) saying: "If you suffer a surprise attack from the enemy then say: 'Ha Min, they will not be victorious.'" There is something on this topic from Salamah bin Al-Akwa'. This is how some of them reported it from Abu Ishaq, the same as the narration of Ath-Thawri. And it has been reported from him, from Al-Muhallab bin Abi Sufrah from the Prophet (ﷺ) in Mursal form.

"During the year of the conquest, when the Prophet (ﷺ) reached Marr Zahran, he told us that we would meet the enemy. So he ordered us to break the fast, and we broke our fast." This Hadith is Hasan Sahih, and there is something on this topic from Ibn 'Umar.

That he heard the Prophet (ﷺ) saying: "Seek your weak for me. For indeed you sustenance and aid is only by your weak." This Hadith is Hasan Sahih.
