Praise be to Allah.
Are breast implants permissible in Islam?
There is nothing wrong with breast implants or enlargement for one who has had a breast removed or who is suffering because they are small, because that comes under the heading of removing a fault or restoring something to the way it was created by Allah.
The evidence for that is the report narrated by Abu Dawud (4232), al-Tirmidhi (1770) and al-Nasai (5161) from ‘Abd al-Rahman ibn Tarafah, that the nose of his grandfather ‘Arjafah ibn As‘ad was cut off in the battle of al-Kulab, and he wore a nose made of silver , but it began to stink, so the Prophet (blessings and peace of Allah be upon him) told him to get a nose made of gold. This hadith was classed as hasan by al-Albani in Saheeh Abi Dawud.
Is botox haram in Islam?
It is permissible to use botox if it is free from harm, because the Prophet (blessings and peace of Allah be upon him) said: “There should be neither harm nor reciprocating harm.” Narrated by Ahmad (2865), Ibn Majah (2341) and classed as sahih by al-Albani in Sahih Ibn Majah.
And Allah knows best.
