عَنْ حَجَّاجِ بْنِ حَجَّاجٍ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ مَا يُذْهِبُ عَنِّي مَذَمَّةَ الرَّضَاعِ قَالَ غُرَّةٌ عَبْدٌ أَوْ أَمَةٌ
It is narrated from Sayyiduna Hajjaj (may Allah be pleased with him), he says: I said: O Messenger of Allah! What is it that can fulfill the right of the wet nurse from me? The Prophet (peace and blessings be upon him) said: A slave or a slave-girl.
