The Messenger of Allah ﷺ gave a decision on the basis of an oath and a single witness.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَضَى بِيَمِينٍ وَشَاهِدٍ  

'Amr said: In the rights (of the people).  

عَمْرٌو فِي الْحُقُوقِ  

The Prophet ﷺ gave a decision on the basis of an oath and a single witness. Abu Dawud said: Al-Rabi' bin Sulaiman al-Mu'adhdhin told me some additional words in this tradition: Al-Shafi'i told me from 'Abd al-'Aziz. I then mentioned it fo Suhail who said: Rabi'ah told me - and he is reliable in my opinion - that I told him this (tradition) and I do not remember it. 'Abd al-'Aziz said: Suhail suffered from some disease which caused him to lose a little of his intelligence, and he forgot some of his traditions. Thereafter Suhail would narrate traditions from Rabi'ah on the authority of his father.  

أَنَّ النَّبِيَّ ﷺ قَضَى بِالْيَمِينِ مَعَ الشَّاهِدِ  

I then met Suhail and asked him about this tradition. He said: I do not know it. I said to him: Rabi'ah transmitted it to me from you. He said: If Rabi'ah transmitted it to you from me, then retransmit it from Rabi'ah on my authority.  

عَنْ رَبِيعَةَ بِإِسْنَادِ أَبِي مُصْعَبٍ وَمَعْنَاهُ قَالَ سُلَيْمَانُ فَلَقِيتُ سُهَيْلاً فَسَأَلْتُهُ عَنْ هَذَا الْحَدِيثِ فَقَالَ مَا أَعْرِفُهُ فَقُلْتُ لَهُ إِنَّ رَبِيعَةَ أَخْبَرَنِي بِهِ عَنْكَ قَالَ فَإِنْ كَانَ رَبِيعَةُ أَخْبَرَكَ عَنِّي فَحَدِّثْ بِهِ عَنْ رَبِيعَةَ عَنِّي  

The Messenger of Allah ﷺ sent an army to Banu al-Anbar. They captured them at Rukbah in the suburbs of at-Ta'if and drove them to the Holy Prophet ﷺ. I rode hurriedly to the Holy Prophet ﷺ and said: Peace be on you, Messenger of Allah, and the mercy of Allah and His blessings. Your contingent came to us and arrested us, but we had already embraced Islam and cut the sides of the ears of our cattle. When Banu al-Anbar arrived, the Holy Prophet ﷺ said to me: Have you any evidence that you had embraced Islam before you were captured today? I said: Yes. He said: Who is your witness? I said: Samurah, a man from Banu al-Anbar, and another man whom he named. The man testified but Samurah refused to testify. The Holy Prophet ﷺ said: He (Samurah) has refused to testify for you, so take an oath with your other witness. I said: Yes. He then dictated an oath to me and I swore to the effect that we had embraced Islam on a certain day, and that we had cut the sides of the ears of the cattle. The Holy Prophet ﷺ said: Go and divide half of their property, but do not touch their children. Had Allah not disliked the wastage of action, we should not have taxed you even a rope. Zubayb said: My mother called me and said: This man has taken my mattress. I then went to the Holy Prophet ﷺ and informed him. He said to me: Detain him. So I caught him with a garment around his neck, and stood there with him . Then the Holy Prophet ﷺ looked at us standing there. He asked: What do you intend (doing) with your captive? I said: I shall let him go free if he returns to this (man) the mattress of his mother which he has taken from her. He said: Prophet of Allah ﷺ, I no longer have it. He said: The Holy Prophet ﷺ took the sword of the man and gave it to me, and said to him: Go and give him some sa's of cereal. So he gave me some sa's of barley.
