Al-Adab Al-Mufrad, Book 27, Hadith 479 (English) ⓘ

Anas ibn Malik reported that the Prophet, may Allah bless him and grant him peace, said, "If the Final Hour comes while you have a palm-cutting in your hands and it is possible to plant it before the Hour comes, you should plant it."

حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ‏:‏ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ هِشَامِ بْنِ زَيْدِ بْنِ أَنَسِ بْنِ مَالِكٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ‏:‏ إِنْ قَامَتِ السَّاعَةُ وَفِي يَدِ أَحَدِكُمْ فَسِيلَةٌ، فَإِنِ اسْتَطَاعَ أَنْ لاَ تَقُومَ حَتَّى يَغْرِسَهَا فَلْيَغْرِسْهَا‏.‏
