Points to ponder about to understand the hikmats of the way Allahu te'ala endowed Islam on human beings:
1- Allahu ta'aalaa sent His orders in human words conveyed by Gebrail alayhissalaam to His Rasuuls (in their specific mother tongues) whom He chose to save His human creatures (naass) from Jahannam and lead to Jannah. Although He has the power and capacity to send His orders to each one of His human creatures, He did not do so.
2- Allahu ta'aalaa bestowed Companions (as-Sahaaba-e-kiraam, radiy Allaahu 'anhum ajma'een) upon His Rasuul, 'alayhissalaam, to help His Rasuul to carry out the most valuable deed of calling the naass to His Jannah. The Deen of Islaam has been made known to the human beings by as-Sahaaba, radiyAllaahu 'anh, their disciples, the taabe'een, the a-immat-ul-mujtehedeen of the ahl-as-sunnah, rahmat-ullaahe 'aleyh, who very carefully collected the details concerning Islaam.
3- There have been people and publications striving to disseminate true Islaam all over the world throughout the history, as there have been those doing just the opposite.
4- Hence, in this world, the haq and baatil are mixed, confused.
5- Islaam has assigned each sane ('aaqil and baaligh) human being, himself or herself, to search for truth with ıkhlaas (sincere devotion and open mind) and pray and supplicate to Allaahu ta'aalaa to lead him or her to the right path, the real, true Islam; as expressed in the suurat-al-Faateha.
