صحيح مسلم 979

Nu'man b. Bashir reported:The Messenger of Allah (may peace-be upon him) used to straighten our rows as it lie were straightening an arrow with their help until be saw that we had learnt it from him. One day he came out, stood up (for prayer) and was about to say: Allah is the Greatest, when he saw a man, whose chest was bulging out from the row, so he said: Servants of Allah, you hint straighten your rows or Allah would create dissension amongst you

Rapporté par Nu'man b. Bashir رضي الله عنه : Le Messager d’Allah ﷺ alignait nos rangs comme on aligne une flèche, jusqu’à ce qu’il voie que nous avions appris de lui. Un jour, il est sorti, s’est mis debout pour la prière et allait dire : “Allah est le plus grand”, quand il a vu un homme dont la poitrine dépassait du rang. Il a dit : « Serviteurs d’Allah, alignez vos rangs, sinon Allah mettra la discorde entre vous. »
