Al-Adab Al-Mufrad, Book 42, Hadith 973 (English) ⓘ

'Abdu'r-Rahman ibn Razin said, "We passed by az-Zubda and were told, 'There is Salama ibn al-Akwa'. I went to him and he greeted us. Then he brought out his hands and stated, 'With these two hands I offered allegiance to the Messenger of Allah, may Allah bless him and grant him peace.' He held out his palm which was as huge as a camel's foot, and we got up and kissed it."

حَدَّثَنَا ابْنُ أَبِي مَرْيَمَ، قَالَ‏:‏ حَدَّثَنَا عَطَّافُ بْنُ خَالِدٍ قَالَ‏:‏ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ رَزِينٍ قَالَ‏:‏ مَرَرْنَا بِالرَّبَذَةِ فَقِيلَ لَنَا‏:‏ هَا هُنَا سَلَمَةُ بْنُ الأَكْوَعِ، فَأَتَيْنَاهُ فَسَلَّمْنَا عَلَيْهِ، فَأَخْرَجَ يَدَيْهِ فَقَالَ‏:‏ بَايَعْتُ بِهَاتَيْنِ نَبِيَّ اللهِ صلى الله عليه وسلم، فَأَخْرَجَ كَفًّا لَهُ ضَخْمَةً كَأَنَّهَا كَفُّ بَعِيرٍ، فَقُمْنَا إِلَيْهَا فَقَبَّلْنَاهَا‏.‏
