Surah: 17   Aya: 36

  Translation

36. And follow not (O man i.e., say not, or do not or witness not, etc.) that of which you have no knowledge (e.g. one's saying: "I have seen," while in fact he has not seen, or "I have heard," while he has not heard). Verily! The hearing, and the sight, and the heart, of each of those you will be questioned (by Allâh).
