Taraweeh, i‘tikaf and Lailatul Qadr
Taraweeh
The night prayer of Ramadan, after ‘Isha and before witr. The Prophet ﷺ led it a few nights and then stopped, lest it become obligatory; from ‘Umar's time it has been prayed in congregation. Eight or twenty rak‘ahs — both have a basis; what matters is praying calmly and with attention.
I‘tikaf
Staying in the mosque for the last ten days. The Prophet ﷺ did it every year, and twenty days in his last. The point is to step out of the world's business and turn wholly to Allah.
Lailatul Qadr
A night better than a thousand months. Look for it in the odd nights of the last ten: the 21st, 23rd, 25th, 27th and 29th.
اللَّهُمَّ إِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّيAllahumma innaka ‘afuwwun tuhibbu al-‘afwa fa‘fu ‘anniO Allah, You are forgiving and love to forgive, so forgive me.
‘A’ishah (ra) asked what to say if she found that night. He taught her this — not a list of wishes, only forgiveness.
