إِنَّ اللهَ يَبْتَلِي عِبَادَهُ عِنْدَ الاْعْمَالِ السَّيِّئَةِ بِنَقْصِ الَّثمَرَاتِ، وَحَبْسِ الْبَرَكَاتِ، وَإِغْلاَقِ خَزَائِنِ الْخَيْرَاتِ، لِيَتُوبَ تَائِبٌ، وَيُقْلِعَ مُقْلِعٌ، وَيَتَذَكَّرَ مُتَذَكِّرٌ، وَيَزْدَجِرَ مُزْدَجِرٌ. وَقَدْ جَعَلَ اللهُ سُبْحَانَهُ الاسْتِغْفَارَ سَبَباً لِدُرُورِ الرِّزْقِ وَرَحْمَةِ الْخَلْقِ، فَقَالَ: ﴿اسْتَغْفِرُوا رَبَّكُمْ إِنَّهُ كَانَ غَفَّارًا. يُرْسِلِ السَّمَاءَ عَلَيْكُم مِّدْرَارًا. وَيُمْدِدْكُم بِأَمْوَالٍ وَبَنِينَ وَيَجْعَل لَّكُمْ جَنَّاتٍ وَيَجْعَل لَّكُمْ أَنْهَارًا.﴾
Certainly, Allāh tries his creatures in respect of their evil deeds by decreasing fruits, holding back blessings and closing the treasures of good, so that he who wishes to repent may repent, he who wishes to turn away (from evils) may turn away, he who wishes to recall (forgotten good) may recall, and he who wishes to abstain (from evil) may abstain. Allāh, the Glorified, has made the seeking of (His) forgiveness a means for the pouring down of livelihood and mercy on the people as Allāh has said: “. . . Seek ye the forgiveness of your Lord! Verily, He is the Most forgiving, He will send (down) upon you the cloud raining in torrents, and help you with wealth and sons (children) . . .” (Qur’ān, 71:10—12)
