*32) After warning the disbelievers of the consequences of their opposition to the truth and their stubbornness, the address now turns to the believers and the Holy Prophet.
*33) That is, they did not call Allah their Lord merely incidentally, nor were they involved in the error to regard Allah as their Lord and at the same time others 'as well as their lords, but they embraced the Faith sincerely and stood by it steadfastly: neither adopted a creed contrary to it later nor mixed it up with a false creed, but they fulfilled the demands of the doctrine of Tauhid in their practical lives as well. "Standing steadfast on Tauhid" has been explained by the Holy Prophet and the eminent Companions thus: Hadrat Anas has reported that the Holy Prophet said: "Many people called Allah their Lord, but most of them became disbelievers. Firm and steadfast is he who remained firm on this creed till his death." (Ibn Jarir, Nasa'i, Ibn Abi Hatim). Hadrat Abu Bakr Siddiq (may Allah be pleased with him) has explained it thus: "Then he did not associate another with Allah: did not attend to any other deity beside Him. " (Ibn Jarir). Hadrat `Umar (may Allah be pleased with him) once recited this verse on the pulpit and said: "By God, the steadfast are those who remained firm on obedience to Allah: did not run about from place to place like foxes." (Ibn Jarir). Hadrat 'Uthman (may Allah be pleased with him) says "Performed his deeds sincerely for the sake of Allah only." (Kashsaf) Hadrat `Ali (may Allah be pleased with him) says: "Performed the duties enjoined by Allah faithfully and obediently." (Kashshaf)
*34) It is not necessary that the coming down of the angels may be perceptible, and the believers may see them with the eyes, or hear their voices with the ears. Although Allah also sends the angels openly for whomever He wills, generally their coming down for the believers, especially in hard times when they are being persecuted by the enemies of the Truth, takes place in imperceptible ways and their voices penetrate into the depths of the heart as peace and tranquility instead of just striking the ear-drums. Some commentators have regarded this coming down of the angels as restricted to the time of death or grave, or the Plain of Resurrection. But if the conditions in which these verses were sent ' down arc kept in view there remains no doubt that the real object of stating this thing here is to mention the coming down of the angels on those who struggle with their lives in this world in the cause of the Truth, so that they are consoled and encouraged and they rest assured that they are not helpless but the angels of Allah are at their back. Although the angels also come to receive the believers at the time of death and they also welcome them in the grave (in the state of bearzakh), and They will also accompany them constantly on the Day of Resurrection, from the time Resurrection takes place till their entry into Paradise, yet their company is not particularly restricted to the Hereafter but remains available in this world also. The context clearly shows that in the conflict between the Truth and falsehood just as the worshippers of falsehood are accompanied by the devils and mischievous people, so arc the believers accompanied by the angels. On the one hand, the companions of the worshippers of falsehood show their misdeeds seem fair to them and assure them that the tyrannical and dishonest acts that they are committing arc the very means of their success and through them only will their leadership and dominance remain safe in the world. On the other, the angels come down to the worshippers of the Truth and give them the message that is being mentioned in the following sentences.
*35) These are very comprehensive words, which contain a new theme of consolation and peace for the believers, in every stage of life, from the world till the Hereafter. This counsel of the angels in this world means: "No matter' how strong and powerful be the forces of falsehood, you should not be afraid of them, and whatever hardships and deprivations you may have to experience on account of your love of the Truth, you should not grieve on account of them, for ahead there lie in store for you such things against which every blessing of the world is insignificant." When the angels say the same words at the time of death, they mean this: "There is no cause of fear for you in the destination you are heading for, for Paradise awaits you there, and you have no cause of grief for those whom you are leaving behind in the world, for we are your guardians and companions here." When the angels will say these very words in the intermediary state between death and Resurrection and in the Plain of Resurrection, they will mean: `Here, there is nothing but peace for you. Do not grieve for the hardships you had to suffer in the world, and do not fear what you are going to face in the Hereafter, for we are giving you the good news of Paradise, which used to be promised to you in the world.
