English Translation of Hadith
Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) used to observe Itikaf every year (during Ramadan) for ten days; in the year in which he passed away, he observed Itikaf for twenty days.
[Al-Bukhari Book 03, Chapter 33, Hadith # 260].
Lesson : as mentioned above in Surah Luqman Ayat " Our beloved Prophet [SAWW](PBUH) were preparing himself for meeting with Allah (SWT) and We learn from these Ahadith that the observance of Itikaf in the last ten days of Ramadan is Sunnah of the Prophet [SAWW](PBUH). But it can be done only in mosque not at home. Itikaf helps to enhance one’s spiritual growth and to strive hard to worship Allah better as there is nothing to distract one’s attention from this noble pursuit.
