336. hadíth
وَ فِي رِوَايَةِ اَلسَّكُونِيِّ بِإِسْنَادِهِ قَالَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: «اِعْتِكَافُ عَشْرٍ فِي شَهْرِ رَمَضَانَ يَعْدِلُ حَجَّتَيْنِ وَ عُمْرَتَيْنِ».
In a narration from Al-Sakuni, with his chain of transmission, it is reported that the Messenger of Allah (swt) (peace and blessings be upon him and his family) said: "Performing i'tikaf for ten days in the Month of Ramadan is equivalent to two Hajj and two Umrah."
