1251. hadíth
فَوَ الَّذِي فَلَقَ الْحَبَّةَ، وَبَرَأَ النَّسَمَةَ، مَا أَسْلَمُوا وَلَكِنِ اسْتَسْلَمُوا، وَأَسَرُّوا الْكُفْرَ، فَلَمَّا وَجَدُوا أَعْوَاناً عَلَيْهِ أَظْهَرُوهُ.
By Him Who broke open the seed (for growing) and created living beings, they had not accepted Islam but they had secured safety (by verbally professing it) and had hidden their misbelief. Consequently when they found helpers for their misbelief they disclosed it.
