Abu Yahya Khuraim bin Fatik (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "He who makes a contribution in Allah's way, will have his reward seven hundred times recorded to his credit."

[At-Tirmidhi].

وعن أبي يحيي خريم بن فاتك رضي الله عنه قال: قال رسول الله ﷺ : "من أنفق نفقة في سبيل الله كتب له سبعمائة ضعف" ((رواه الترمذي وقال: حديث حسن)).
