«لولا أن أشق على أمتي لفرضت عليهم السواك مع الوضوء ولأخرت العشاء الآخرة إلى نصف الليل»
The Prophet (peace and blessings be upon him) said:
"Were I not afraid of causing hardship to my Ummah, I would have made the miswak obligatory upon them along with ablution, and I would have delayed the Isha prayer until midnight."
