It was said to ʿUmar, "Will you appoint your successor?" ʿUmar said, "If I appoint a Caliph (as my successor) it is true that somebody who was better than I (i.e., Abu Bakr) did so, and if I leave the matter undecided, it is true that somebody who was better than I (i.e., Messenger of Allah ﷺ) did so." On this, the people praised him. ʿUmar said, "People are of two kinds: Either one who is keen to take over the Caliphate or one who is afraid of assuming such a responsibility. I wish I could be free from its responsibility in that I would receive neither reward nor retribution I won't bear the burden of the caliphate in my death as I do in my life." (Using translation from Bukhārī 7218)
إِنْ أَتْرُكْ فَقَدْ تَرَكَ مَنْ هُوَ خَيْرٌ مِنِّي رَسُولُ اللهِ ﷺ وَإِنْ أَسْتَخْلِفْ فَقَدِ اسْتَخْلَفَ مَنْ هُوَ خَيْرٌ مِنِّي أَبُو بَكْرٍ ؓ قَالَ فَأَثْنَوْا عَلَيْهِ فَقَالَ رَاغِبٌ وَرَاهِبٌ لَا أَتَحَمَّلُهَا حَيًّا وَمَيِّتًا لَوَدِدْتُ أَنِّي نَجَوْتُ مِنْهَا كَفَافًا لَا لِي وَلَا عَلَيَّ
