Ever wondered whether a formula “adds up”? This tool answers one plain question: do the units match? Pick a couple of quantities (distance, time, a speed…), join them with ×, ÷, +, or =, and press Run. It works out the resulting unit — for example distance ÷ time gives a speed, LT⁻¹ (metres per second) — and flags anything that can’t be right, like adding a length to a time.

- S2.1essenceThe Qurʾān commands prayer in general; the Sunnah specifies its manner and times.
- S2.2essenceThe unbroken consensus of every generation confirms the obligation.
- S2.3essenceAnalogy extends the established ruling to cases the primary texts did not name.
