This message is intended for all youth whom Allah (Exalted be He) has guided to hold fast to religion, propagate Islam, and understand religion in all countries. I recommend them to fear Allah (Exalted be He), and ascertain things wisely apart from haste. I recommend them to give much care to recite, reflect, revise, and learn the Glorious Qur'an. I also advise them to memorize, take care of, and study the Sunnah of the Messenger of Allah (peace be upon him). I recommend them to call to Allah (Exalted be He), enjoin good, and forbid evil with wisdom, and maintain good behavior and speech, not through violence and severity but through lenience and insightfulness.
Allah (Glorified and Exalted be He) says: Invite (mankind, O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴـﻪ ﻭ ﺳـﻠﻢ) to the Way of your Lord (i.e. Islâm) with wisdom (i.e. with the Divine Revelation and the Qur'ân) and fair preaching, and argue with them in a way that is better.
I recommend them not to rush things, make sure of all matters, consult one another, and cooperate for good in order to understand the religion as it should be.
The Messenger (peace be upon him) said: "If Allah wants to do good to a person, He makes him comprehend the religion."
Haste may lead to great evil, so it is obligatory to ascertain things, seek the Shar`y proofs, and attend the sessions of scholars who are known for their Istiqamah (integrity) and good `Aqidah (creed).
