Surah Al-Isra' (The Night Journey), Verse 29

وَلَا تَجْعَلْ یَدَكَ مَغْلُوْلَةً اِلٰی عُنُقِكَ وَلَا تَبْسُطْهَا كُلَّ الْبَسْطِ فَتَقْعُدَ مَلُوْمًا مَّحْسُوْرًا ۟

Wa laa taj'al yadaka maghloolatan ilaa 'unuqika wa laa tabsut haa kullal basti fataq'uda maloomam mahsooraa

“Make not thy hand tied (like a niggard's) to thy neck, nor stretch it forth to its utmost reach, so that thou become blameworthy and destitute.”
