"I heard the Messenger of Allah ﷺ saying: 'No Imam closes his door on one in need, dire straits and poverty, except that Allah closes the gates of the Heavens from his dire straits, his needs, and his poverty.' So Mu'awiyah appointed a man to look after the needs of the people." (Using translation from Tirmidhī 1332)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَا مِنْ إِمَامٍ أَوْ وَالٍ يُغْلِقُ بَابَهُ دُونَ ذَوِي الْحَاجَةِ وَالْخَلَّةِ وَالْمَسْكَنَةِ إِلَّا أَغْلَقَ اللهُ أَبْوَابَ السَّمَاءِ دُونَ حَاجَتِهِ وَخَلَّتِهِ وَمَسْكَنَتِهِ قَالَ فَجَعَلَ مُعَاوِيَةُ رَجُلًا عَلَى حَوَائِجِ النَّاسِ
