[Machine] When Abu Bakr intended to appoint Umar as his successor, he sent for him and asked him to come. When Umar arrived, Abu Bakr said to him, "I invite you to a challenging task, for the one who is in charge of it. Fear Allah, O Umar, in His obedience and obey Him with piety. Indeed, the one who is God-fearing is safe and protected. Then, know that this matter, only those who act upon it can attain it. So, whoever commands what is right and acts upon falsehood, and commands what is good and acts upon evil, his hopes will soon be cut off and his deeds will be in vain. If you become their leader, if you are able to withhold your hand from shedding their blood, and withhold your stomach from consuming their wealth, and withhold your tongue from violating their honor, then do so, for there is no power except with Allah."  

لَمَّا أَرَادَ أَبُو بَكْرٍ ؓ أَنَّ يَسْتَخْلِفَ عُمَرَ بَعَثَ إِلَيْهِ فَدَعَاهُ فَأَتَاهُ فَقَالَ «إِنِّي أَدْعُوكَ إِلَى أَمْرٍ مُتْعِبٍ لِمَنْ وَلِيَهُ فَاتَّقِ اللهَ يَا عُمَرُ بِطَاعَتِهِ وَأَطِعْهُ بِتَقْوَاهُ فَإِنَّ الْمُتَّقِيَ آمِنٌ مَحْفُوظٌ ثُمَّ إِنَّ الْأَمْرَ مَعْرُوضٌ لَا يَسْتَوْجِبُهُ إِلَّا مَنْ عَمِلَ بِهِ فَمَنْ أَمَرَ بِالْحَقِّ وَعَمِلَ بِالْبَاطِلِ وَأَمَرَ بِالْمَعْرُوفِ وَعَمِلَ بِالْمُنْكِرِ يُوشِكُ أَنَّ تَنْقَطِعَ أُمْنِيَّتُهُ وَأَنْ يَحْبَطَ عَمَلُهُ فَإِنْ أَنْتَ وُلِّيتَ عَلَيْهِمْ أَمْرَهُمْ فَإِنِ اسْتَطَعْتَ أَنْ تَجِفَّ يَدُكَ مِنْ دِمَائِهِمْ وَأَنْ تَضْمُرَ بَطْنُكَ مِنْ أَمْوَالِهِمْ وَأَنْ يَجِفَّ لِسَانُكَ عَنْ أَعْرَاضِهِمْ فَافْعَلْ وَلَا قُوَّةَ إِلَّا بِاللهِ»
