Setting
1- The Prophet (may Allah's peace and blessings be upon him) used to observe I‘tikāf [spiritual retirement in the mosque] during each Ramadan for ten days. The year in which he died, he observed I‘tikāf for twenty days.
2- The Messenger of Allah (may Allah's peace and blessings be upon him) used to practice I‘tikāf in the last ten nights of Ramadan until he passed away; then, his wives followed this practice after him
3- O Messenger of Allah, I had vowed, before embracing Islam, to make I‘tikāf for one night – another narration reads: for one day – the Sacred Mosque. He said: Then fulfill your vow.
4- Whoever was in I‘tikāf with me should stay in I‘tikāf the last ten; for I was informed of that night, but I was then made to forget it. I saw myself prostrating in water and mud in its morning. So, seek it in the last ten
5- The devil circulates in the son of Adam like blood. I feared lest he should cast evil thoughts in your hearts
