أَفِى قُلُوبِهِم مَّرَضٌ أَمِ ٱرْتَابُوٓا۟ أَمْ يَخَافُونَ أَن يَحِيفَ ٱللَّهُ عَلَيْهِمْ وَرَسُولُهُۥ ۚ بَلْ أُو۟لَٰٓئِكَ هُمُ ٱلظَّٰلِمُونَ

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