601. hadíth
كَتَبَ مُحَمَّدُ بْنُ اَلْحَسَنِ اَلصَّفَّارُ رَضِيَ اَللَّهُ عَنْهُ إِلَى أَبِي مُحَمَّدٍ اَلْحَسَنِ بْنِ عَلِيٍّ عَلَيْهِ اَلسَّلاَمُ: فِي اَلْوُقُوفِ وَ مَا رُوِيَ فِيهَا عَنْ آبَائِهِ عَلَيْهِمُ اَلسَّلاَمُ فَوَقَّعَ عَلَيْهِ اَلسَّلاَمُ "اَلْوُقُوفُ تَكُونُ عَلَى حَسَبِ مَا يُوقِفُهَا أَهْلُهَا إِنْ شَاءَ اَللَّهُ تَعَالَى".
Muhammad ibn Al-Hasan Al-Saffar, may Allah (swt) be pleased with him, wrote to Abu Muhammad Imam Hasan ibn Ali Al-Askari (a.s), peace be upon him, regarding endowments (awqaf) and what has been narrated about them from his forefathers (a.s), peace be upon them. Imam (a.s) replied: "Endowments are to be managed according to how their owners have designated them, if Allah (swt), the Exalted, wills."
