Continuation of the previous question regarding the emergence of al-Mahdi and the descent of 'Isa (peace be upon him).

The Shaykh : ... Today, for example, we know with certainty that one of the afflictions of the Muslim world is being engrossed in this worldly life; and among the effects of this engrossment is making lawful what Allah (Mighty and Majestic) has forbidden, such as riba (usury or interest) through the slightest of ruses, let alone other forbidden things. Can these people, if al-Mahdi emerges or 'Isa (peace be upon him) descends, be used to fight the disbelievers, or can the disbelievers be fought with them? The answer is no. Therefore, it is obligatory for all Muslims in every land of Islam to first act upon the understanding of Islam, and that it be a correct understanding, and secondly to apply it to themselves, their families, and their children. So that when al-Mahdi comes or 'Isa descends, he finds the people in no need of repairing what this long period has corrupted, but rather finds them in need of a successful, inspired man to lead them to jihad in the path of Allah. Islam commands us to work and forbids us from being complacent and relying on individuals. Rather, we work so that if the day comes, we find ourselves prepared. And I say, if 'Isa (peace be upon him) descended now, he would not be able to work with the Muslims except by doing what the Messenger (peace and blessings be upon him), the master of the prophets and messengers, did with his people. Without that, whereas the Messenger (peace be upon him) rose, their number was limited and few. Today, the Muslims are millions and millions. If he finds the Muslims in this state, finding them scattered in groups, with divided beliefs and paths, and so on, when will he be able to rectify this corruption and unify this division, and so on?
