By Allah, this world (is so insigni- ficant in comparison) to the Hereafter that if one of you should dip his finger- (and wnile saying this Yahyg pointed with his forefinger) -in the ocean and then he should see as to what has stuck to it. This hadith has been narrated through another chain of transmitters also but with a slight variation of wording.  

قَالَ رَسُولُ اللَّهِ ﷺ وَاللَّهِ مَا الدُّنْيَا فِي الآخِرَةِ إِلاَّ مِثْلُ مَا يَجْعَلُ أَحَدُكُمْ إِصْبَعَهُ هَذِهِ وَأَشَارَ يَحْيَى بِالسَّبَّابَةِ فِي الْيَمِّ فَلْيَنْظُرْ بِمَ يَرْجِعُ وَفِي حَدِيثِهِمْ جَمِيعًا غَيْرَ يَحْيَى سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ ذَلِكَ وَفِي حَدِيثِ أَبِي أُسَامَةَ عَنِ الْمُسْتَوْرِدِ بْنِ شَدَّادٍ أَخِي بَنِي فِهْرٍ وَفِي حَدِيثِهِ أَيْضًا قَالَ وَأَشَارَ إِسْمَاعِيلُ بِالإِبْهَامِ
