Aisha reported: Some men among the rough bedouins came to the Prophet, peace and blessings be upon him, and they said, “When is the Hour?” The Prophet looked to the youngest of them and he said, “If this boy lives, he will not reach old age before your Hour is established.”

عَنْ عَائِشَةَ قَالَتْ كَانَ رِجَالٌ مِنْ الْأَعْرَابِ جُفَاةً يَأْتُونَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَيَسْأَلُونَهُ مَتَى السَّاعَةُ فَكَانَ يَنْظُرُ إِلَى أَصْغَرِهِمْ فَيَقُولُ إِنْ يَعِشْ هَذَا لَا يُدْرِكْهُ الْهَرَمُ حَتَّى تَقُومَ عَلَيْكُمْ سَاعَتُكُمْ
