Sunan Ibn Majah, Hadith 2760 ⓘ
It was narrated from Thawban that the Messenger of Allah said: “The best Dinar that a man can spend is a Dinar that he spends on his family, a Dinar that he spends on a horse in the cause of Allah, and a Dinar that a man spends on his companions in the cause of Allah.”
حَدَّثَنَا عِمْرَانُ بْنُ مُوسَى اللَّيْثِيُّ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَبِي أَسْمَاءَ، عَنْ ثَوْبَانَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَفْضَلُ دِينَارٍ يُنْفِقُهُ الرَّجُلُ دِينَارٌ يُنْفِقُهُ عَلَى عِيَالِهِ وَدِينَارٌ يُنْفِقُهُ عَلَى فَرَسٍ فِي سَبِيلِ اللَّهِ وَدِينَارٌ يُنْفِقُهُ الرَّجُلُ عَلَى أَصْحَابِهِ فِي سَبِيلِ اللَّهِ " .
