15 —FIRST VOLUME, 71st LETTER
This letter, written to Khân-i Khânân’s son Mirzâ Dârâb, informs that showing gratitude to Allâhu ta’âlâ is to be done by adapting oneself to Islam:
May Allâhu ta’âlâ increase your stamina and help you! Both reason and Islam confirm that he who does favours should be thanked. The degree of the gratitude is dependent upon the amount of the blessing coming. The greater the blessing, the greater the necessity to express gratitude. As is seen, the rich should be more grateful than the poor, depending on the degree of wealth. It is for this reason that the poor ones of this Ummat will go into Paradise five hundred years earlier than the rich.
To thank Allâhu ta’âlâ, it is necessary to have a belief compatible with what the savants of Ahl as-sunnat taught. For, it is only this group who will be saved from Hell. After correcting the belief, it is necessary to act compatibly with Islam. Islam should be learned from the books of the mujtahids of this group. [It should not be learned from a muftî who is a reformer, who knows nothing of Islam, from an unlearned hâfiz, or from the misguiding writings of irreligious people, which are written in newspapers under the pretence of praising Islam in order to deceive young people.] Then the turn comes to tasfiya and tezkiya on the way shown by great Sunnite men of Tasawwuf.
There are great benefits in this third stage of gratitude, though it is not obligatory. But the first two stages are obligatory. For, these two are the base, the essence of Islam. Islam perfects and matures an individual by means of the third stage. Everything outside these three stages, which are the belief of Ahl as-sunnat, the commandments of Islam, and progress along the way of great men of Tasawwuf, is nothing but sinning, disobedience and ingratitude, including troublesome mortifications and vehement struggles. Ancient Indian Brahmins and Greek philosophers engaged in great acts of mortification. Yet, because they did not adapt themselves to Prophets ‘’alaihimussalâm’, all their practices were sins rather than acts of thanksgiving to Allâhu ta’âlâ. None of them were accepted. In the next world they will not be saved from Hell. Then, hold fast to the way of our Sayyid, of our Master, of our Saviour, of our Intercessor for the forgiveness of our sins, of our Specialist who cures our hearts and souls, that is, of our Master Muhammad Rasûlullah ‘sall-Allâhu ’alaihi wa ’alâ âlihi wa sallam’, and to the way of his four Khalîfas! His four Khalîfas ‘ridwânullâhi ta’âlâ ’alaihim ajma’în’ are the guides along the way to salvation, who will conduct you to happiness. Allâhu ta’âlâ will bless those who walk along this way.
[To say, “May Allah bless you,” does not mean to say that He will bless you even though you are in this state. It means to say, “May He correct your morals and deeds and change you into a state by which He will bless you!”]
