وَلَا تَجْعَلْ يَدَكَ مَغْلُولَةً إِلَىٰ عُنُقِكَ وَلَا تَبْسُطْهَا كُلَّ ٱلْبَسْطِ فَتَقْعُدَ مَلُومًا مَّحْسُورًا
Wa laa taj'al yadaka maghloolatan il 'unuqika wa laa tabsut haa kullal basti fataq'uda maloomam mahsooraa
Do not be tight-fisted, nor so open-handed that you end up blamed and overwhelmed with regret.
And do not keep your hand chained to your neck, nor stretch it out to its fullest reach, or you will sit blamed and destitute.
