“Indeed, in Paradise there is a river called Rajab; its water is whiter than milk and sweeter than honey. Whoever fasts one day in Rajab, Allah will give him to drink from that river.”
"إِنَّ فِى الجَنَّةِ نَهْرًا يُقَالُ له رَجَبٌ، ماؤُهُ أشَدُّ بَيَاضًا مِنَ الَّلبَنِ، وَأَحْلَى مِنَ العَسَل مَن صَامَ يوْمًا من رَجَب سَقَاهُ اللَّه مِنْ ذَلك النَّهرِ".
