SubhanAllah! The immediate use of contraception may sometimes result in permanent infertility, which is a serious matter.

As for the issue of work, I do not see it as a valid excuse for delaying pregnancy or using birth control. In my view—Allāh knows best—this is not a sufficient justification for postponing childbirth. Rather, if Allāh grants the blessing of conception, one should rejoice. Nowadays, people travel to different countries seeking medical solutions for infertility, and some may even resort to prohibited methods such as in-vitro fertilisation or using the sperm of a strange man. They invest vast sums of money in pursuit of having children. So do not deliberately obstruct this divine blessing. Allāh, the Almighty, says: "And Allāh has made for you spouses from among yourselves, and from your spouses He has granted you children and grandchildren, and provided you with good things. Will they then believe in falsehood and deny the blessings of Allāh?" [Sūrah An-Naḥl 16:72] Thus, children are a great blessing when Allāh grants them righteousness. Thus, this reason is not a valid excuse—Allāh knows best—if one can take leave during pregnancy or work in a manner that avoids exposure to certain chemicals, this would be a better approach than resorting to contraceptive methods...The use of contraception carries certain risks. However, if a woman genuinely deems it necessary for a valid reason, then the preferable option would be ‘azl (withdrawal), as it is safer, better, and preferable, provided there is mutual agreement between spouses. Afterward, they may reassess their situation. Nevertheless, if a woman chooses to use contraceptive methods such as patches applied to the body, she must ensure their removal before performing ghusl (ritual purification). If such a barrier remains in place, her purification—whether from major ritual impurity (janābah) or menstruation—would not be valid. And Allāh knows best."

Still, he does not view it as a valid excuse. 3⃣. If a woman has a legitimate reason to use the patch, would her ghusl still be valid? Sheikh Abdulḥamīd Az-Zu'kari ḥafidhahullāh said: "Yes, it is sufficient to either pour water over it or wipe over it. As for the bleeding, it should be examined: if it has the characteristics of menstrual blood, then it is considered menstruation. However, if it is merely irregular bleeding, then it is classified as istiḥāḍha (non-menstrual bleeding)." Source: https://t.me/womensbenefits/710
