I'tikaf in Ramadan
Muwatta Malik #734
كتاب الاعتكاف
وَحَدَّثَنِي زِيَادٌ، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ، كَانَ يَقُولُ مَنْ شَهِدَ الْعِشَاءَ مِنْ لَيْلَةِ الْقَدْرِ فَقَدْ أَخَذَ بِحَظِّهِ مِنْهَا.
Ziyad related to me from Malik that he had heard that Said ibn al-Musayyab used to say, “Whoever is present at isha on Laylat al-Qadr has taken his portion from it.”
