TABARANI 1301:
from Jaʿfar b. Tamīm b. al-ʿAbbās or Ibn Tammām b. al-ʿAbbās from his father —
[Machine] The Messenger of Allah ﷺ said, "Why do I see you coming to me with unkempt hair? If it were not difficult for my ummah (community), I would have made it obligatory for them to use the tooth stick (siwak) just as the prayer is obligated upon them."
الطبراني ١٣٠١:
عن جعفر بن تميم بن العباس oر ابن تمام بن العباس عن أبيه —
قَالَ رَسُولُ اللهِ ﷺ «مَا لِي أَرَاكُمْ تَأْتُونِي قُلْحًا اسْتَاكُوا فَلَوْلَا أَنْ أَشُقَّ عَلَى أُمَّتِي لَفَرَضْتُ عَلَيْهِمُ السِّوَاكَ كَمَا فُرِضَتْ عَلَيْهِمُ الصَّلَاةُ»
