Talaq
طَلَاق
Islamic Law
Divorce by the husband, effected by pronouncing the divorce formula. There are three types: Talaq Raj'i (revocable — husband can return to wife within iddah without new nikah), Talaq Ba'in Sughra (after iddah expires — requires new nikah to remarry), and Talaq Ba'in Kubra (after three pronouncements — cannot remarry unless wife marries another man in a genuine marriage which ends naturally). Triple talaq in one sitting is either counted as one (majority Sunni position today) or three (older position). The Prophet ﷺ said talaq is the most hated of permitted things to Allah.
Testosterone
Medical
The primary male sex hormone, produced in the testes (men) and adrenal glands/ovaries (women). In men, testosterone drives libido, energy, muscle mass, and confidence. In women, testosterone (at much lower levels) also drives desire and motivation. Testosterone declines with age, stress, poor sleep, and obesity. Low testosterone (in men or women) is associated with low libido, fatigue, and depression — all treatable with medical support. Islam's emphasis on health maintenance aligns with protecting hormonal health.
