Shaykh Al-Islam Ibn Al-Qayyim said: Complete felicity is to be found in the True Religion, by implementing it in speech and deed. Those who follow this religion are the ones who attain felicity as Allah, Exalted is He, says, “Guide us to the Straight Path; the path of those whom You have favoured; not [the path] of those whose portion is anger not those who have gone astray.” (al-Fatihah 1:6-7) “… They are the people guided by their Lord, they are the successful” (al-Baqarah 2:5) “…and if there should come to you guidance from Me – whoever follows My guidance will neither go astray nor suffer” (Ta Ha 20:123) “…and when guidance comes to You from Me, whoever follows My guidance – there will be no fear concerning them, nor shall they grieve” (al-Baqarah 2:38) “The truly good will be in perfect Bliss and the dissolute will be in the Blazing Fire” (al-Infitar 82:13-14)
The promise that the followers of guidance and righteous deeds will be in perfect Bliss in the Hereafter, and the threat that the disbelievers and sinners will be in torment in the Hereafter, is something that all the Messengers have agreed upon. However we shall mention a beneficial point here. People often see, and hear of, the believers being afflicted with adversity and tribulation, and conversely they often see, and hear of, the disbelievers attaining leadership and wealth in this world. This leads them to believe that well-being in this world is only reserved for the disbelievers and only a fraction of it is given to the believers; and also to believe that nobility and might is for the disbelievers in this world and for the believers in the Hereafter.
When such a person, who believes in the truth of the Qur’an hears verses such as, “…but all might belongs to Allah and to His Messenger and to the believers.” (al-Munafiqun 63:8) “It is Our army which will be victorious” (as-Saffat 37:173) “Allah has decreed, ‘I will be victorious, I and My Messenger'” (al-Mujadilah 58:21) “The successful outcome is for those who have taqwa” (al-Araf 7:128), he believes they refer to the Hereafter only and this belief is further strengthened when he sees the disbelievers and hypocrites vanquishing and subjugating the Muslims. If such as person is asked why Allah allowed this to happen to his Awliya, his beloved friends, and those who follow the truth, he will reply in one of two ways. If he is of those who do not believe that the Actions of Allah arise from wisdom and benefit, he will reply by saying that Allah does what He wills, “He will not be questioned about what He does, but they will be questioned.” (al-Anbiya 21:23) If, on the other hand, he does believe that the actions of Allah are dictated by wisdom and benefit, he will reply by saying that this happens so that they may actualise sabr and attain the reward of the Hereafter, and that reward without measure that is meted out to the patient, along with achieving exalted ranking.
Both these groups go on to address various issues, problems and queries concerning their belief, answering them in accordance to the level of their cognisance, or ignorance as the case may be, of Allah, His Names and Attributes, many times causing the heart to boil in horror at what they say! We have witnessed many incidents from these people, and other cases have been conveyed to us, whereby they end up accusing the Lord, Exalted is He, of plain oppression and other things that could only arise from an enemy of Allah! Al-Jahm used to go out with his followers to lepers and people facing adversity and say, ‘Look at them! Could the Most Merciful of the merciful do this?’ intending thereby to reject the Attribute of Mercy just as he had rejected the Attribute of Wisdom. Another person used to say, ‘There is no one who harms the creation more than the Creator’…
More than one person has said to me, ‘When I repent to Him and work righteous deeds, He restricts my provision and makes life difficult. When I return to sin and submit to my lusts, provision and ease come freely to me.’ I say to them, ‘This is a test from Allah so that He may see your truthfulness and patience. Are you truthful in turning to Him and going to Him, are you able to bear His trial with patience so that the end will be for you; or are you untruthful in your repentance?’
These false thoughts and statements are but upon two foundations:
The first: the servant thinking well of himself and his religious practice, his believing that he has fulfilled what is obligatory upon him to do and leave what is prohibited for him to do; all of this coupled with the belief that his enemy or opponent has not done this, believing that he himself is more deserving of Allah and His Messenger than he.
The second: his belief that Allah, Glorious is He, could quite possibly not aid the follower of the True Religion and not appoint him any sort of success in this world, instead having him live a life of subjugation and oppression, this despite his establishing what Allah has commanded of him; inwardly and outwardly.
There is none worthy of worship besides Allah! How many ignorant servants, how many devout people with no insight, how many people claimed to be scholars yet possess no knowledge of the reality of this religion, have been corrupted by this deception!
