How to Attain Sincerity
As-Saree (may Allah have mercy on him) said:
لاَ تَعْمَلْ للِنَّاسِ شَيْئاً
Don't do anything for the sake of people!
وَ لاَ تَتْرُكْ لَهُمْ شَيْئاً
And don't stop doing things because of them!
وَ لاَ تُغَطِّ لَهُمْ شَيْئاً
And don't hide anything from them!
وَ لاَ تَكْشِفْ لَهُمْ شَيْئاً
And don't reveal anything to them!
