ما هو تكملة الحديث الشريف: "أرحم أمتي بأمتي أبو بكر"؟

The Hadith in question is authentic, narrated by Al-Tirmidhi from Anas bin Malik, from the Prophet (peace be upon him): "The most merciful of my Ummah towards my Ummah is Abu Bakr; the strongest of them in the command of Allah is Umar; the most truthful of them in modesty is Uthman; the most knowledgeable of them concerning lawful and unlawful is Mu'adh ibn Jabal; the best of them in apportioning shares of inheritance is Zayd ibn Thabit; the best reciter among them is Ubayy; and for every nation there is a trustee, and the trustee of this Ummah is Abu Ubaydah ibn al-Jarrah." Al-Albani graded it as authentic.
