"...and from here, we see that the method of the various callers in seeing to the upbringing of the youth is very successful. This method consists of giving a given youth a small bit of knowledge every week, then asking him: 'Did you act according to what you have learned this week?' and repeating this the week after, and the week after that, etc. You build him up in a gradual manner. Every time he rises a level, you give him a greater task, and greater responsibility. You do this to the point that his soul becomes ripe enough that you can finally say to him: 'Now is the time for Jihad. Would you like to perform Jihad?'
This method is the divine method to see to the upbringing of the human soul.
So, a youth can live in a state of jahiliyyah, and then return to Allah - the Exalted and Majestic - as the result of some traumatic event in his life: he survives a terrible car accident, his mother dies, Allah - the Mighty and Majestic - shows him a dream...in any case, he returns to Allah, the Mighty and Majestic. He reads about Abu Bakr, and how he used to do this and that, and suddenly, he looks to the people around him, thinking: 'this person is a liar; this person tried stealing from me,' - he wishes to put down all the people around him! All of the Muslims around him! Why? Because they are not like Abu Bakr. He finds nobody besides Abu Bakr - from all of the Companions of the Prophet - to compare the people to. Do you expect everybody to be like Abu Bakr? They will never be like Abu Bakr. The best person after the Messenger of Allah is Abu Bakr. The Companions, themselves, said: "We did not
hold anyone to be like Abu Bakr, then 'Umar, then 'Uthman, then 'Ali. After them, we would look at the rest of the Companions without preferring one over another."
As for you, you expect all of humanity to be at the same level of zuhd as 'Umar. There is no zuhd like the zuhd of 'Umar. Maybe one, five, ten people in this Ummah can acheive this level of zuhd. But, to expect everyone to be at this level? This is not realistic. Do you expect all of them to be at the level of generosity of 'Uthman? There is only a very small number of people...but, everyone having the bravery of 'Ali? The firmness of Abu Bakr? No. Only a very small group can have this.
...كَذَٲلِكَ ڪُنتُم مِّن قَبۡلُ فَمَنَّ ٱللَّهُ عَلَيۡڪُمۡ فَتَبَيَّنُوٓاْۚ...
"...Likewise, were you yourselves, before Allah conferred on you His favors (i.e. guided you). Therefore, be cautious in discrimination..."
Yesterday, you were driving around the streets in your car, chasing after girls. Is this not so? This is how you were. So, you, as Allah has conferred on you, and allowed you to return to Him, He can also confer on this person, and allow this disobedient one to repent.
This youth who wishes to hit this person, discipline that person, reveal the faults of another person, insult another person...why? He does this out of the burning he feels in his heart for Islam. He has returned to Allah - the Mighty and Majestic - while his blood is boiling. However, if he had the least bit of knowledge, he wouldn't have done any of this. If he had some Shar'i knowledge, he wouldn't have come in front of the people, revealing his faults. Instead, he would have come to him privately, saying: 'By Allah, my brother, I used to be a disobedient, fasiq sinner. But, Allah bestowed His favors upon me, and I saw some deviance from you, a small mistake, a big mistake, in such-and-such a matter, and I just wanted to draw your attention to it, because I love you, and I don't want you to be punished for it on the Day of Resurrection.' This is better than that you come in front of the people, saying: 'Fulan is a fasiq! This person is such-and-such! That person is this, and this person is that!' This is the method of the ignorant, and if the Messenger of Allah had done this, 'Umar would never have entered into Islam, nor would many others. He would've just said: 'Kill 'Umar, and relieve us,' back when 'Umar was fighting against him. However, despite the fact that they were enemies to him, and were harming and torturing him, whenever the hardship became more unbearable, he would simple say: "O Allah! Forgive my people, for they do not know."
Therefore, it is a must for the da'i to learn this Religion, and how to work for this Religion. Just as he acts, he must know, and if he doesn't know, he must ask those who know. However, nobody is good enough for him in this world, at all. You say to him: 'Ask Shaykh such-and-such!' He replies: 'This Shaykh is a sinner!' 'This Shaykh is a fasiq!' 'This Shaykh is from the slaves of the tawaghit!' 'And this one...!'
OK, so, who is left in the world, then?"
