Tirmidhi says: Abu Hafs Amr bin Ali Al-Fallas narrated to us, he says: Yahya bin Saeed Al-Qattan narrated to us, Yahya Al-Qattan says that Mughira bin Abi Qurrah Al-Sudusi narrated to us, Mughira says: I heard Anas bin Malik say that a man asked: O Messenger of Allah! Should I tie my camel and trust in Allah, or should I leave it untied? The Prophet replied: "Tie your camel, then trust in Allah."

Falas says: Yahya bin Saeed Al-Qattan says that in my view, this hadith is munkar (denounced).

Tirmidhi says: This hadith is gharib through this chain; we know the hadith of Anas only through this chain. A similar hadith is narrated marfu‘an from ‘Amr bin Umayyah ad-Damri.

Tirmidhi says: We have compiled this book "Sunan al-Tirmidhi" briefly in the hope of benefit. We pray to Allah Almighty that it may be beneficial, that He makes it beneficial for us by His mercy, and that by His mercy He does not make it a cause of harm for us. Ameen.

(1) Sunan al-Tirmidhi (187) (The word «وَلا سَفَرٍ» is present in some copies of ‘Ilal, but in Sahihain and Tirmidhi it is without it).
(2) Sunan al-Tirmidhi (1444).
(3) Both hadiths are authentic. The purpose of Imam Tirmidhi in mentioning the reason (‘illah) for both hadiths is that he has mentioned those evidences which show that both are abrogated.
