﴿ لَقَدْ مَنَّ ٱللَّهُ عَلَى ٱلْمُؤْمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولًۭا مِّنْ أَنفُسِهِمْ يَتْلُوا۟ عَلَيْهِمْ ءَايَٰتِهِۦ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ ٱلْكِتَٰبَ وَٱلْحِكْمَةَ وَإِن كَانُوا۟ مِن قَبْلُ لَفِى ضَلَٰلٍۢ مُّبِينٍ ﴾

“Indeed, God bestowed a favour upon the believers when he raised up in their midst an apostle from among themselves, to convey His messages unto them, and to cause them to grow in purity, and to impart unto them the divine writ as well as wisdom - whereas before that they were indeed, most obviously, lost in error.”

The example set by the Prophet throughout his life must be followed by all reformers till Doomsday. For the task of reformation to be successful, it is essential that the targeted people should feel as if the reformer is one of themselves in every respect. His language, his style of speaking, his style of living— all should be familiar to them. No such feelings should be created between him and his addressee that may lead, in one way or another, to the latter becoming distanced from him, or to the addressee and the reformer becoming rivals. The first task to be performed among the people is to foster in them the ability to read the signs of God spread everywhere within and without their own selves. God’s signs should become part of their very mental make-up. The second task is to purify people. This end is achieved by the reformer speaking to them in person and giving them the opportunity to spend time in his company. The message can, of course, be put across through general discourses and writing, but this would only be in principle; whereas by resorting to individual communication the message can be conveyed in a more precise and detailed way. Then there is the question of the personality of the dayee, which should always lend weight to the message. Individual meetings thus serve the purpose of the purification of the addressees, or madu‘. The third task is to introduce to the madu‘ the shariah—the book of guidance on how life should be led in this world. The fourth task is to impart wisdom, that is, to unveil the secrets of religion and to highlight the truths hidden between the lines.
