عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((أُعْطِيتُ مَا لَمْ يُعْطَ أَحَدٌ مِنَ الْأَنْبِيَاءِ)) فَقُلْنَا: يَا رَسُولَ اللَّهِ! مَا هُوَ؟ قَالَ: ((نُصِرْتُ بِالرُّعْبِ وَأُعْطِيتُ مَفَاتِيحَ الْأَرْضِ وَسُمِّيتُ أَحْمَدَ وَجُعِلَ التُّرَابُ لِي طَهُورًا وَجُعِلَتْ أُمَّتِي خَيْرَ الْأُمَمِ))
Sayyiduna Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: I have been given things which were not given to any prophet. We asked: O Messenger of Allah! What are those? He (peace and blessings be upon him) said: I have been helped with awe, the keys of the earth have been given to me, my name has been kept Ahmad, the earth has been made a purifier for me, and my Ummah has been made the best of all communities.
