Way of preaching and counseling
Nahj al-Balāgha|Volume 1|Book 1|Chapter 81
أَيُّهَا النَّاسُ، الزَّهَادَةُ قِصَرُ الاْمَلِ، وَالشُّكْرُ عِنْدَ النِّعَمِ، والورعُ عِنْدَ الْـمَحَارِمِ، فَإِنْ عَزَبَ ذلِكَ عَنْكُمْ فَلاَ يَغْلِبِ الْحَرَامُ صَبْرَكُمْ، وَلاَ تَنْسَوْا عِنْدَ النِّعَمِ شُكْرَكُمْ، فَقَدْ أَعْذَرَاللهُ إِلَيْكُمْ بِحُجَجٍ مُسْفِرَةٍ ظَاهِرَةٍ، وَكُتُبٍ بَارِزَةِ الْعُذْرِ وَاضِحَةٍ.
O people! abstinence is to shorten desires, to thank for bounties and to keep off prohibitions. If this is possible then (at least) the prohibitions should not overpower your patience; and do not forget gratitude when receiving blessings For Allāh has exhausted the excuses before you through clear, shining arguments and open, bright books.
