Yahya related to me from Malik that Zayd ibn Aslam had said that Ubayda ibn al-Jarrah had written to Umar ibn al-Khattab mentioning to him a great array of Byzantine troops and the anxiety they were causing him. Umar ibn al-Khattab wrote in reply to him, "Whatever hardship befalls a believing slave, Allah will make an opening for him after it, and a hardship will not overcome two eases. Allah the Exalted says in His Book, 'O you who trust, be patient, and vie in patience; be steadfast and fear Allah, perhaps you will profit.' " (Sura 3 ayat 200).  

مالك:٢١-٦ – وَحَدَّثَنِي عَنْ مَالِكٍ عَنْ زَيْدِ بْنِ أَسْلَمَ قَالَ كَتَبَ أَبُو عُبَيْدَةَ بْنُ الْجَرَّاحِ إِلَى عُمَرَ بْنِ الْخَطَّابِ يَذْكُرُ لَهُ جُمُوعًا مِنَ الرُّومِ وَمَا يَتَخَوَّفُ مِنْهُمْ فَكَتَبَ إِلَيْهِ عُمَرُ بْنُ الْخَطَّابِ أَمَّا بَعْدُ فَإِنَّهُ مَهْمَا يَنْزِلْ بِعَبْدٍ مُؤْمِنٍ مِنْ مُنْزَلِ شِدَّةٍ يَجْعَلِ اللَّهُ بَعْدَهُ فَرَجًا وَإِنَّهُ لَنْ يَغْلِبَ عُسْرٌ يُسْرَيْنِ وَأَنَّ اللَّهَ تَعَالَى

يَقُولُ فِي كِتَابِهِ يَا أَيُّهَا الَّذِينَ آمَنُوا اصْبِرُوا وَصَابِرُوا وَرَابِطُوا وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُفْلِحُونَ

quran:3:200 –

O you who have believed, persevere and endure and remain stationed and fear Allah that you may be successful.  

O you who believe, be patient, in ˹performing˺ acts of obedience, in the face of afflictions and in refraining from acts of disobedience, and vie in patience, with the disbelievers, lest they be more patient than you; be steadfast, persist in the struggle; fear God, in all of your circumstances, so that you will prosper, ˹so that˺ you will win ˹admittance to˺ Paradise and be delivered from the Fire.

يَا أَيُّهَا الَّذِينَ آمَنُوا اصْبِرُوا وَصَابِرُوا وَرَابِطُوا وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُفْلِحُونَ  

{يا أيها الذين آمنوا اصبروا} على الطاعات والمصائب وعن المعاصي {وصابروا} الكُفَّار فلا يكونوا أشد صبرا منكم {ورابطوا} أقيموا على الجهاد {واتقوا الله} في جميع أحوالكم {لعلَّكم تفلحون} تفوزون بالجنة وتنجون من النار.
