Hadith on Leadership: Muslim leaders should appoint people to take care of the people’s needs, or else Allah will neglect their needs

Amr ibn Murrah said to Mu’awiyah: I heard the Messenger of Allah, peace be upon him, say, “There is no leader who closes the door to someone in need, one suffering in poverty, except that Allah closes the gates of the heavens from him when he is suffering in poverty.” So Mu’awiyah appointed a man to look after the needs of the people.
[Sunan At-Tirmidhi, Book of Judgments, Number 1332, Hasan]

قَالَ عَمْرُو بْنُ مُرَّةَ لِمُعَاوِيَةَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَا مِنْ إِمَامٍ يُغْلِقُ بَابَهُ دُونَ ذَوِي الْحَاجَةِ وَالْخَلَّةِ وَالْمَسْكَنَةِ إِلَّا أَغْلَقَ اللَّهُ أَبْوَابَ السَّمَاءِ دُونَ خَلَّتِهِ وَحَاجَتِهِ وَمَسْكَنَتِهِ فَجَعَلَ مُعَاوِيَةُ رَجُلًا عَلَى حَوَائِجِ النَّاسِ
