Nahj al-Balāgha
Hadith 1653إِنَّمَا قَالَ (صلى الله عليه وآله وسلم) ذَلِكَ وَالدِّينُ قُلٌّ فَأَمَّا الْآنَ وَقَدِ اتَّسَعَ نِطَاقُهُ وَضَرَبَ بِجِرَانِهِ فَامْرُؤٌ وَمَا اخْتَارَ.
The Prophet (S) said this at a time when the religion was confined to a few, but now that its expanse has widened and it is firmly settled everyone is free in his action. [1]
