✦ The night of Shab e Qadr may be on 27 most probably

----------------------

✦ Zirr bin Habaish Radi Allahu Anhu reported I thu asked Ubayy bin Ka'b Radi Allahu Anhu Your brother (in faith) Ibn Mas'ud Radi Allahu Anhu says He who stands (for the night prayer) throughout the year would find Lailat-ul-Qadr, whereupon he said: May Allah have mercy upon him; (he said these words) with the intention that people might not rely only (on one night), whereas he knew that it (Lailat-ul-Qadr) is in the month of Ramadan and it is the twenty-seventh night. He then took oath (without making any exception, i. e. without saying In sha Allah) that it was the twenty-seventh night. I said to him: Abu Mundhir, on what ground do you say that? Thereupon he said: By the indication or by the sign which the Messenger of Allah (ﷺ) gave us, and that is that on that day (the sun) would rise without having any ray in it.
