عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي رَافِعٍ عَنْ أَبِيهِ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَذَّنَ فِي أُذُنَيِ الْحَسَنِ حِينَ وَلَدَتْهُ فَاطِمَةُ بِالصَّلَاةِ
It is narrated from Sayyiduna Abu Rafi’ (may Allah be pleased with him), he says: When Sayyidah Fatimah (may Allah be pleased with her) gave birth to Sayyiduna Hasan (may Allah be pleased with him), I saw the Messenger of Allah (peace and blessings be upon him and his family) that he gave the call to prayer (adhan) in both of his ears.
