Chapter on the Virtue of Charity
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 1|Chapter 20
وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: «لاَ تَقْطَعُوا عَلَى اَلسَّائِلِ مَسْأَلَتَهُ فَلَوْ لاَ أَنَّ اَلْمَسَاكِينَ يَكْذِبُونَ مَا أَفْلَحَ مَنْ يَرُدُّهُمْ».
The Messenger of Allah سبحانه وتعالى صلى الله عليه وعلى آله وسلم said: "Do not interrupt the request of a beggar, for if it were not for the fact that some of the needy lie, those who turn them away would never prosper."
