17:29
وَلَا تَجْعَلْ يَدَكَ مَغْلُولَةً إِلَىٰ عُنُقِكَ وَلَا تَبْسُطْهَا كُلَّ ٱلْبَسْطِ فَتَقْعُدَ مَلُومًا مَّحْسُورًا
walā tajʿal yadaka maghlūlatan ilā ʿunuqika walā tabsuṭ'hā kulla l-basṭi fataqʿuda malūman maḥsūran
Do not be tight-fisted, nor so open-handed that you end up blamed and overwhelmed with regret.
And let not your hand be tied (like a miser) to your neck, nor stretch it forth to its utmost reach (like a spendthrift), so that you become blameworthy and in severe poverty.
