Regarding Payment In Advance
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى، وَابْنُ، مَهْدِيٍّ قَالاَ حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي الْمُجَالِدِ، وَقَالَ عَبْدُ الرَّحْمَنِ، عَنِ ابْنِ أَبِي الْمُجَالِدِ، بِهَذَا الْحَدِيثِ قَالَ عِنْدَ قَوْمٍ مَا هُوَ عِنْدَهُمْ . قَالَ أَبُو دَاوُدَ الصَّوَابُ ابْنُ أَبِي الْمُجَالِدِ وَشُعْبَةُ أَخْطَأَ فِيهِ .
The tradition mentioned above has also been transmitted by Ibn Abi al-Mujahid through a different chain of narrators. This version has: "to those people who did not possess these things." Abu Dawud said: What is correct is Ibn Abi al-Mujahid. Shu'bah made a mistake in it.
