الْمَالُ وَالْبَنُونَ زِينَةُ الْحَيَاةِ الدُّنْيَا ۖ وَالْبَاقِيَاتُ الصَّالِحَاتُ خَيْرٌ عِندَ رَبِّكَ ثَوَابًا وَخَيْرٌ أَمَلًا
Wealth and children are the adornments of the present life. But the things that last, the virtuous deeds, are better with your Rabb for reward, and better for hope. (Surah Kahf, verse: 46)
Good deeds have a huge reward, and their benefits are seen in this worldly life in addition to the immense rewards that wait in the Akhirah.
When we are disobedient to Allah, our life becomes riddled with difficulties, depression etc.
