Narrated Abu Qatadah:The Prophet (sal Allaahu alayhi wa sallam) said: When any one of you urinates, he must not touch his penis with his right hand, and when he goes to relieve himself he must not wipe himself with his right hand (in the privy), and when he drinks, he must not drink in one breath
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Our source also lists this ruling under Muhammad Muhyi Al-Din Abdul Hamid, the editor of the printed edition it was taken from. It is al-Albani's ruling printed again, so it is counted once.
