Sahih Muslim, 6116

Rapporté par Amir b. Sa’d d’après son père رضي الله عنه : Le Messager d’Allah ﷺ a dit : « Le plus grand pécheur parmi les musulmans est celui qui pose une question au sujet d’une chose qui n’était pas interdite, et qui, à force d’insister, la voit interdite à cause de lui. »

Amir b. Sa'd reported on the authority of his father that Allah's Messenger (ﷺ) said:The greatest sinner amongst the Muslims is one who asked about a thing (from Allah's Apostle) which had not been forbidden for the Muslims and it was forbidden for them because of his persistently asking about it
