أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ ، عَنْ هَمَّامٍ ، عَنْ قَتَادَةَ ، عَنْ الْحَسَنِ ، عَنْ عُقْبَةَ بْنِ الْعَامِرِ ، قَالَ : قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" عُهْدَةُ الرَّقِيقِ ثَلَاثَةُ أَيَّامٍ ".
فَفَسَّرَهُ قَتَادَةُ : إِنْ وَجَدَ فِي الثَّلَاثِ عَيْبًا رَدَّهُ بِغَيْرِ بَيِّنَةٍ، وَإِنْ وَجَدَهُ بَعْدَ ثَلاثَةٍ، لَمْ يَرُدَّهُ إِلَّا بِبَيِّنَةٍ

Yazid bin Harun told us, on the authority of Hammam, on the authority of Qatada, on the authority of Al-Hasan, on the authority of Uqba bin Al-Amir, he said: The Prophet, may God bless him and grant him peace, said He said: “The slave’s custody is for three days.”
Qatada explained it: If he finds a defect in the three, he should return it without proof, and if he finds it after three, he should not return it except with proof.
