Observe witr with a single rak'ah and make a prostration as long as you would take to recite fifty verses before raising your head.

This hadith emphasizes the importance of observing witr prayer, which is an optional prayer that Muslims can perform at night. It involves standing up and reciting certain verses from the Quran, followed by bowing down in prostration for a period of time equal to reciting fifty verses. After this, one should stand up again and complete the rest of their prayers. This hadith also teaches us that we should be mindful when performing our prayers, taking care to ensure that we are doing them correctly and with full concentration. Additionally, it reminds us to be patient when praying; even if it takes longer than usual or if we feel tired or distracted during our prayers, we should still strive to complete them properly.
