Allah SWT says: وَهُوَ الَّذِى جَعَلَ لَكُمُ النُّجُومَ لِتَهْتَدُوا بِهَا فِى ظُلُمٰتِ الْبَرِّ وَالْبَحْرِ ۗ قَدْ فَصَّلْنَا الْءَايٰتِ لِقَوْمٍ يَعْلَمُونَ "And it is He who placed for you the stars that you may be guided by them through the darknesses of the land and sea. We have detailed the signs for a people who know." (QS. Al-An'aam: Verse 97) * Via the Beautiful Qur'an http://goo.gl/QLwc8B
