The Promised Massih Hadhrat Ahmad (as) writes:
“Let it be known that it is the established custom of Allah that whenever a Messenger, a Prophet or an appointed recipient of Divine Revelation is sent for the reformation of mankind, it becomes imperative that he is accompanied by such angels who instill guidance in all loving hearts. They induce the hearts towards goodness. They continue to descend until the darkness of profanity and corruption gives way to the break of the dawn of faith and truthfulness. The Almighty God says: “The angels and the Spirit descend upon them by the command of their Lord with their Lord’s decrees concerning every matter. It is all peace, till the break of the dawn”. (Surah Al Qadr, 97:5-6) .
So the appearance of the angels and the Holy Spirit only takes place at the advent of a person of distinction, who is dressed in the garb of Khilafat and honored with a direct communion with God. This Khalifa is specially gifted with the Holy Spirit and the angels in attendance are deputed to descend on all pious hearts. The reflection of this heavenly glow falls on people of receptive talent, and consequently the whole world is engulfed in the dazzle of this intense light.
As a result of the noble influence of the angels, the hearts of such people are voluntarily inclined towards virtuous thoughts and are thus charmed by the concept of the Unity of God. Upright hearts are charged with the inclination towards the search of truth. The spiritually frail are granted fortitude. Everywhere a breeze begins to blow which is supportive to the objectives of the Mujaddid. An invisible hand is beckoning humanity so that they of themselves are hastening towards that reform which will bring out the best of their talents. Mankind is in a state of agitation and stir in anticipation of what is to come.
