Punishment in the grave for a grave sin which people belittle

Once the Prophet (ﷺ) went through the grave-yards of Medina and heard the voices of two humans who were being tortured in their graves. The Prophet (ﷺ) said, “They are being punished, but they are not being punished because of a major sin, yet their sins are grave. One of them used not to keep himself from (being soiled with) urine, and the other used to go about with calumnies (namima).” Then the Prophet asked for a green palm tree leaf and split it into two pieces and placed one piece on each grave, saying, “I hope that their punishment may be abated as long as these pieces of the leaf are not dried.”

Purification is the key to prayer and many, if not most people don’t know it’s rulings. Especially women regarding their menses.

I want to change that and give women the essentials they need to know about menses. It is more complicated than many women think as it is often oversimplified erroneously.
