Assalamu alaikum wa rehmatullahi wa barakatuh
We, Ever We, created them, and We have upheld their frames; and when We (so) decide, We will exchange their likes, an (easy) exchange. (Surah Dahr 28)
The verse speaks very clearly about the changes which would take place in the skeleton of a person once he is created,the skeleton which consists of the bones and joints.
It is a fact that the number of joints as well as the bones is more at the time of birth and decreases with age.It is not consistent.See
See the following ahadees.
“Aisha reported Allah’s Messenger (may peace be upon him) as saying: Every one of the children of Adam has been created with three hundred and sixty joints; so he who declares the Glory of Allah, praises Allah, declares Allah to be One, Glorifies Allah, and seeks forgiveness from Allah, and removes stone, or thorn, or bone from people’s path, and enjoins what is good and forbids from evil, to the number of those three hundred and sixty-four, will walk that day having removed himself from Hell. (Translation of Sahih Muslim, The Book of Zakat (Kitab Al-Zakat), Book 005, Number 2199)”
Narrated Buraydah ibn al-Hasib: “I heard the Apostle of Allah peace_be_upon_him) say: A human being has three hundred and sixty joints for each of which he must give alms. The people asked him: Who is capable of doing this? He replied: It may be mucus in the mosque which you bury, and something which you remove from the road; but if you do not find such, two rak’ahs in the forenoon will be sufficient for you. (Translation of Sunan Abu-Dawud, General Behavior (Kitab Al-Adab), Book 41, Number 5222)”
The ahadees mention:
The maximum number of joints could be up to 364.
The number of 360 – 364 comes with the word creation, i.e. the man is created with 360 number of joints.This word clearly points towards the fact that the number of joints at birth would be different.The science now says the same that the number of bones and joints decreases with age.See
The alms giving is associated with the greatest number of joints which are provided.
