That the Messenger of Allah ﷺ said: "The most virtuous of charitable spending is the shade of a tent in the cause of Allah, or giving a servant in the cause of Allah, or a riding camel in the cause of Allah." (Using translation from Tirmidhī 1627)
"أفضلُ الصدقاتِ: ظِلُّ فُسْطاطٍ في سبيل الله، أو مِنْحَةُ خادمٍ في سبيل الله، أو طَرُوقَةُ فَحْلَ في سبيل الله" .
