[Machine] The Prophet ﷺ sent Mu'adh to Yemen and he said, "O Messenger of Allah, advise me." He said, "You must have Taqwa (fear of Allah) as much as you can, and remember Allah at every stone and tree. And when you commit a sin, follow it with repentance, with secrecy if it was done secretly, and with openness if it was done openly."
أَنَّ النَّبِيَّ ﷺ بَعَثَ مُعَاذًا إِلَى الْيَمَنِ فَقَالَ يَا رَسُولَ اللَّهِ أَوْصِنِي قَالَ «عَلَيْكَ بِتَقْوَى اللَّهِ مَا اسْتَطَعْتَ وَاذْكُرِ اللَّهَ ﷻ عِنْدَ كُلِّ حَجَرٍ وَشَجَرٍ وَإِذَا عَمِلْتَ سَيِّئَةً فَأَحْدِثْ عِنْدَهَا تَوْبَةً السِّرُّ بِالسِّرِّ وَالْعَلَانِيَةُ بِالْعَلَانِيَةِ»
