وَعَنِ اِبْنِ مَسْعُودٍ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَا رَضَاعَ إِلَّا مَا أَنْشَزَ اَلْعَظْمَ, وَأَنْبَتَ اَللَّحْمَ. } رَوَاهُ أَبُو دَاوُدَ [1] .
Narrated Ibn Mas'ud (RA): Allah's Messenger (ﷺ) said: "The only suckling (to be considered) is that which gives life to the bones and causes flesh to grow." [Abu Dawud reported it].
