عَنْ أَبِي الدَّرْدَاءِ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مِنْ فِقْهِ الرَّجُلِ رِفْقُهُ فِي مَعِيشَتِهِ
It is narrated from Sayyiduna Abu Darda (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: It is a sign of a man's wisdom that he adopts gentleness, that is, moderation in livelihood.
