Whosoever gave the Bai‘a twice

Narrated Salama:

We gave the oath of allegiance to the Prophet under the tree. He said to me, "O Salama! Will you not give the oath of allegiance?" I replied, "O Allah's Apostle! I have already given the oath of allegiance for the first time." He said, (Give it again) for the second time.

حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ، قَالَ بَايَعْنَا النَّبِيَّ ﷺ تَحْتَ الشَّجَرَةِ فَقَالَ لِي " يَا سَلَمَةُ أَلاَ تُبَايِعُ ". قُلْتُ يَا رَسُولَ اللَّهِ قَدْ بَايَعْتُ فِي الأَوَّلِ. قَالَ " وَفِي الثَّانِي ".
