عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((لَا يُحَرِّمُ مِنَ الرَّضَاعِ الرَّضْعَةُ وَالرَّضْعَتَانِ))
Narrated by Sayyiduna Abdullah bin Zubair (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Suckling once or suckling twice does not make breastfeeding (radā‘at) unlawful.
