حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ، حَدَّثَنَا مُعَاوِيَةُ بْنُ صَالِحٍ، عَنْ كَثِيرِ بْنِ الْحَارِثِ، عَنْ الْقَاسِمِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ عَدِيِّ بْنِ حَاتِمٍ الطَّائِيِّ، أَنَّهُ سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ أَيُّ الصَّدَقَةِ أَفْضَلُ ؟ قَالَ:‏‏‏‏ خِدْمَةُ عَبْدٍ فِي سَبِيلِ اللَّهِ، ‏‏‏‏‏‏أَوْ ظِلُّ فُسْطَاطٍ، ‏‏‏‏‏‏أَوْ طَرُوقَةُ فَحْلٍ فِي سَبِيلِ اللَّهِ ، ‏‏‏‏‏‏قَالَ أَبُو عِيسَى:‏‏‏‏ وَقَدْ رُوِيَ عَنْ مُعَاوِيَةَ بْنِ صَالِحٍ هَذَا الْحَدِيثُ مُرْسَلًا، ‏‏‏‏‏‏وَخُولِفَ زَيْدٌ فِي بَعْضِ إِسْنَادِهِ.

He said, The service of a worshipper in the cause of Allah, or providing the shade of tent, or mount in the cause of Allah. [Abu 'Eisa said:] This Hadith has been reported from Mu'awiyah bin Salih in Mursal form.And Zaid has been contradicted concerning part of its chain. He said: And Al-Walim bin Jamil has reported this Hadith from Al-Qasim Abu 'Abdur-Rahman, from Abu Umamah, from the Prophet (ﷺ).
