The knowledge of the Unseen is only with Allah, Allah alone. Likewise the knowledge of hour ⏳. It is unknown whether the rain will prove useful or harmful; no one can know whether the planter will ultimately enjoy the fruit, which the trees bear because of the rain. So also is the case with Divine Revelation.
Narrated Anas bin Malik: The Prophet (ﷺ) said, “At every womb Allah appoints an angel who says, ‘O Lord! A drop of semen, O Lord! A clot. O Lord! A little lump of flesh.” Then if Allah wishes (to complete) its creation, the angel asks, (O Lord!) Will it be a male or female, a wretched or a blessed, and how much will his provision be? And what will his age be?’ So all that is written while the child is still in the mother’s womb.” [Sahih Bukhari]
Allah سبحانه وتعالى says in the Holy Quran that:
Verily, Allâh alone has the knowledge of the Hour (of Resurrection). He sends down the rain. And He knows what the wombs contain. And nobody knows what he will accomplish on the morrow. And nobody knows the land where he will die. Verily, Allâh (alone) is the All-Knowing, All-Aware. Q31: 34
Note 📝 :
Nobody can guess the time when the condition of people will determine the sending down of Divine Revelation, nor do they ever know the land and the people to whom it will come down.
Who knows whether the unborn child will be hard of luck or enjoy good fortune, whether he will perform virtuous deeds in life or whether he will earn evil.
There are times when a person will be a believer while going to bed at night, but when he gets up in the morning, he is in a state of disbelief.
That is why one is enjoined always to pray to Allâh that he should remain ever steadfast in belief and never falter.
