Praise be to Allah, and may blessings and peace be upon the Messenger of Allah. To proceed:
This claim has no basis in the Qur’an or Sunnah. It has not been established from the scholars that the lines on the palms were created as an indication of the Beautiful Names of Allah or of the age of the Prophet صلى الله عليه وسلم. Rather, it is one of the matters that some people pass around without any religious evidence.
Knowing the Names and Attributes of Allah تعالى is among the noblest branches of knowledge and has one of the greatest effects on faith. The more a servant knows his Lord, His Names, and His Attributes, the greater his faith, love, and veneration of Him become.
However, this is a matter of creed, and therefore it is not permissible to establish anything in this area merely through conjecture, visual observations, or numerical calculations. Rather, reference must be made to the Qur’an, the authentic Sunnah, and what has been established from the scholars.
The Beautiful Names of Allah are not derived from the shapes of things in nature, from the lines of the hand, or from unsupported numerical calculations.
The claim that the lines on the right palm resemble the number 18, while those on the left palm resemble 81, and that their sum is 99, corresponding to the number of the Beautiful Names of Allah, has no evidence.
Likewise, it is not correct to claim that subtracting one number from the other gives 63, and that this number indicates the age of the Prophet صلى الله عليه وسلم.
These are merely numerical coincidences between numbers supposedly derived from the shape of the palm lines. There is no religious text connecting these lines with the Names of Allah تعالى or with the age of the Prophet صلى الله عليه وسلم.
Shaykh Ibn Baz رحمه الله was asked about the claim that the lines of the palm form the numbers 18 and 81, whose sum is 99, corresponding to the number of the Beautiful Names of Allah. He said:
“What some people have said has no basis. We have not been informed that any scholar said this, so it should not be relied upon.”
Shaykh Ibn ‘Uthaymeen رحمه الله was also asked about this claim and what is said about its connection with the story of the women of Egypt in the Surah of Yusuf عليه السلام. He said:
“All of this has no basis; these are part of Allah’s creation.”
This demonstrates that merely finding a resemblance between the shape of some lines and certain numbers is not sufficient to establish a religious or unseen meaning.
Another widespread claim is that the lines found on people’s hands today are the marks resulting from the women of Egypt cutting their hands when they saw Yusuf عليه السلام.
This too has not been established by authentic evidence.
Allah تعالى says concerning them:
﴿When they saw him, they were greatly amazed by him and cut their hands and said, “Perfect is Allah! This is not a human being; this is none but a noble angel.”﴾ [Yusuf: 31].
The verse tells us that they injured their hands, but it contains no indication that the palm lines found on people today are a trace of that event.
A person may sometimes find numerical correspondences or similar shapes in certain things. However, turning these correspondences into religious indications or evidence of unseen matters requires proof.
Religion is not based on such coincidences, because opening this door can lead to attributing meanings to Allah تعالى and His religion without knowledge.
Allah تعالى says:
﴿Say: My Lord has only forbidden immoralities, what is apparent of them and what is concealed, sin, transgression without right, and that you associate with Allah that for which He has not sent down any authority, and that you say about Allah what you do not know.﴾ [Al-A‘raf: 33].
It is not correct to say that the lines on the palms indicate the ninety-nine Beautiful Names of Allah, nor that the numbers 18 and 81 add up to 99, or that their difference, 63, indicates the age of the Prophet صلى الله عليه وسلم.
These claims have no basis in the Qur’an or Sunnah, and nothing of this has been established from the scholars. The lines found on the palms are part of Allah’s creation, and it is not correct to attribute unseen or matters of creed to them without established evidence.
The proper approach regarding the Beautiful Names of Allah and all other matters of creed is to rely on the Qur’an and Sunnah, not on visual similarities, numerical calculations, or speculation.
And Allah knows best.
