And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty) [surah al-Talaq; 65:2]

And whosoever puts his trust in Allah, then He will suffice him [surah al-Talaq;

By no means shall you attain al-birr (righteousness) until you spend (in Allah’s cause) of that which you love [surah al ‘Imran; 3:92]

And give not a thing in order to have more (or consider not your deeds of obedience to Allah as a favour to Allah) [surah al-Muddaththir; 74:6]
