Wa Alaikumus Salam wa Rahmatul Laah wa Barakaatuh, Sister @Safreenarrhh!
Microblading is a form of semi-permanent tattooing that typically lasts around two years. In most cases, It is done using a blade, similar to a razor, to create small incisions in the eyebrow area and deposit pigment to give the appearance of fuller brows. It is closely related to traditional tattooing.
According to the majority scholarly opinion, microblading falls under the category of changing the creation of Allah, which is among the things Satan promised to lead people into, as mentioned in Surah An-Nisaa 4:117-119. Tattooing is explicitly included within this ruling.
Imam al-Qurtubi (May Allah be merciful to him) stated in his tafsir of this verse, 5/392, that a number of scholars held that changing the creation of Allah refers to tattooing and similar practices undertaken for beautification. This view was reported from Ibn Masβud (May Allah be pleased with him) and al-Hasan al-Basri (May Allah have mercy on him).
For these reasons, it is best to avoid microblading, our sister. The best beauty is the natural one.
Indeed, Allah is the All-Knowing.
