(13:38,39)“And indeed We sent Messengers before you, and made for them wives and offspring. And it was not for a Messenger to bring a sign except by Allah's leave. (For) every matter there is a decree (from Allah). (38) Allah blots out what He wills and confirms (what He wills). And with Him is the Mother of the Book.”
[Work has fixed time: Allah Almighty says, ‘As you are a man and a messenger, like you, all the messengers and prophets sent before you, were men and used to eat, go to market place, had wives and children. The Quran says, ‘Say to people, ‘I am but man like yourselves, but the inspiration has come to me, that your God is One God.’
In Bukhari and Muslim there is a tradition in which Prophet of Allah says, ‘What has happened to these people that they say so and so, whereas I observe Prayer and suspend too, I observe Fast and suspend observing them and I marry the women too. He who turns away from my Sunnah, he has no relation with me. There is a Hadith mentioned in Musnad
Ahamad: ‘Four things are the Sunnah of all prophets (be peace upon all of them): 1, circumcision, 2, to apply perfume, 3, to use Miswak, 4, marriage. Allah further says, ‘No prophet could have brought a miracle to his people except by Allah’s permission and will, this matter is only in His control. Surely Allah does what He wills and decides what He wills. For everything there is appointed time and everything has a specific due measure with Allah.’
‘Know you not that Allah knows all that is in the heaven and on the earth, Verily, it is (all) in the Book, verily that is easy for Allah.’
The heavenly Books revealed by Allah were meant for a limited age and period of time, so, He abrogates the books which He wills and confirms which He wills. Thus Allah revealed the Quran to His Messenger (pbuh) which abrogated all the books revealed before it. (Allah blots out what He wills and confirms what He wills), except life, death, misery and happiness (i.e. Faith and disbelief), for, they do not change.
Mansoor says that he asked Mujahid, ‘Some of us say in their supplication, ‘O Allah! If my name is with those who are happy (believers) let it remain among them; and if my name is among the miserable ones (disbelievers), remove it from among them and place it among the happy ones. Is it right to supplicate so?’ Mujahid replied, ‘This supplication is good.’ I met him a year or more later and repeated the same question to him and he recited these verses, ‘We sent it (this Quran) down on a blessed night.’ (44: 3) Mujahid commented next, ‘During Lailatul-Qadr (Night of Decrees), Allah decides what provisions and disasters will occur in the next year. He then brings forward or backward (or blots out) whatever He wills. ‘As for the book containing the records of the happy (believers) and the miserable (disbelievers) does not change.
Shaqeeq bin Salmah used to recite this supplication often, ‘O Allah! If you wrote us among wretched ones, remove this status from us and write us among the blessed ones. If you wrote us among the blessed ones, please let us stay at that way, for surely, you blot out and confirm what you will and with You is the Mother of Book.’
Similar statements were collected from Omar bin Khattab and Abdullah bin Masood (R.A.), indicating that Allah blots out and affirms what He wills in the Book of Records. What further supports the message is that the Messenger of Allah said, ‘A man might be deprived of a provision (that was written for him) because of a sin that he commits; only Supplication changes Al- Qadr (Predestination); and only Birr (righteousness) can increase the life span.’
Maintaining the ties of the womb (kinship) increases the life span. This is also in another Hadith that Supplication and Predestination encounter between the earth and the sky (heaven). Ibn-e Abbas says: ‘Allah has ‘Lauh-e Mahfooz’. It takes five thousand years to get there. It is made of white pearls, between two ruby-lipped covers. Allah Almighty sees to them sixty three times. He blots out and affirms what He wills, with Him is the Mother of the Book.’
Prophet of Allah says, ‘The Book is opened when three last hours of night remain to pass. No one other than Him can see that, He blots out and affirms what He wills.’ Kalbi says that it means He increases life span and the means of substances. He was asked, ‘Who told you this meaning.’ He (pbuh) when he was asked to explain this verse, he said, ‘On Thursday all is written.’ All things that are not related to reward and punishment are removed, i.e. your sayings, I ate, I drank, I went and I came etc. although they are true but not related to reward or punishment, so they all are eradicated. And those words which have concern to them are affirmed.]
