Sahih al-Bukhari · Book 81: To make the Heart Tender (Ar-Riqaq) · About hope and hoping too much
Narrated Anas bin Malik:
حَدَّثَنَا مُسْلِمٌ ، حَدَّثَنَا هَمَّامٌ ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ ، عَنْ أَنَسٍ ، قَالَ خَطَّ النَّبِيُّ صلى الله عليه وسلم خُطُوطًا فَقَالَ " هَذَا الأَمَلُ وَهَذَا أَجَلُهُ، فَبَيْنَمَا هُوَ كَذَلِكَ إِذْ جَاءَهُ الْخَطُّ الأَقْرَبُ " .
The Prophet (ﷺ) drew a few lines and said, "This is (man's) hope, and this is the instant of his death, and while he is in this state (of hope), the nearer line (death) comes to Him."
