Al-Baqara (The Cow) 2:83
وَإِذْ أَخَذْنَا مِيثَاقَ بَنِي إِسْرَائِيلَ لاَ تَعْبُدُونَ إِلاَّ اللّهَ وَبِالْوَالِدَيْنِ إِحْسَاناً وَذِي الْقُرْبَى وَالْيَتَامَى وَالْمَسَاكِينِ وَقُولُواْ لِلنَّاسِ حُسْناً وَأَقِيمُواْ الصَّلاَةَ وَآتُواْ الزَّكَاةَ ثُمَّ تَوَلَّيْتُمْ إِلاَّ قَلِيلاً مِّنكُمْ وَأَنتُم مِّعْرِضُونَ
AND LO! We accepted this solemn pledge from [you,] ' the children of Israel:  "You shall worship none but God; and you shall do good unto your parents and kinsfolk, and the orphans, and the poor; and you shall speak unto all people in a kindly way; and you shall be constant in prayer; and you shall spend in charity. And yet, save for a few of you, you turned away: for you are obstinate folk!
An-Nahl (The Bee) 16:125
ادْعُ إِلِى سَبِيلِ رَبِّكَ بِالْحِكْمَةِ وَالْمَوْعِظَةِ الْحَسَنَةِ وَجَادِلْهُم بِالَّتِي هِيَ أَحْسَنُ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِ وَهُوَ أَعْلَمُ بِالْمُهْتَدِينَ
CALL THOU (all mankind] unto thy Sustainer's path with wisdom and goodly exhortation, and argue with them in the most kindly manner-  for, behold, thy Sustainer knows best as to who strays from His path, and best knows He as to who are the right-guided.

The human body contains about 100 trillion cells, each working together in a complex symphony of interactions. With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's. And in every one of the 100 trillion cells, the sequence of these four letters, or bases, is nearly identical.
