فَإِذَا فَرَغْتَ فَانصَبْ ۝ وَإِلَىٰ رَبِّكَ فَارْغَبْ

The Prophet Muhammad went tirelessly in the quest of knowledge about reality and Truth. God blessed him with this knowledge, which opened his heart to the deep realisation of Truth (ma‘rifah). Then he started preaching the oneness of God in Makkah, where he had to face stiff opposition, but it was thanks to this opposition, that he became known throughout the country. This is God’s law in the present world. Hence, a man has to face difficult conditions (‘usr) in the beginning, but if he perseveres with patience, this ‘usr or hardship becomes a stepping stone to new and easy circumstances (yusr). Therefore, a man should always look towards God and continue to struggle according to his capacity.
