How can a ḥadīth be considered defective when it is found in Ṣaḥīḥ Muslim, such as the ḥadīth of Anas: "They used to begin with 'Al-ḥamdu lillāhi Rabbil-ʿālamīn' (All praise is due to Allah, the Lord of the worlds), not mentioning 'Bismi-llāhi-rraḥmāni-rraḥīm' (In the name of Allah, the Most Gracious, the Most Merciful) at the beginning of the recitation nor at its end"?

The issue of the authenticity of what is mentioned in the Two Sahihs has been detailed in previous fatwas. As for the Hadith of the Seven, Yahya al-Qattan narrated it in two ways: one aligns with the well-known narration, "so that his left hand does not know what his right hand has spent," which is the narration of Al-Bukhari, Malik, and Ahmad. The other way, Yahya made a mistake in it, narrating it with an inversion: "so that his right hand does not know what his left hand has spent," which is the narration of Muslim. Ibn Khuzaymah and some scholars have affirmed Yahya al-Qattan's error in this narration, and this error is called "inverted" (Maqloob), not "interpolated" (Mudraj).
