It is mentioned in the Quran that when Yûsuf ‘alayhis salâm became the king of Egypt and there was a drought, all his brothers came to him asking for food. (At that time they did not know that he was in fact their brother whom they had thrown into the well). He then revealed his true identity to them and gave them his shirt asking them to pass it over their father’s, Ya‘qûb’s ‘alayhis salâm, eyes. He also told them to return with everyone. As a result of passing his shirt over his father’s eyes, his eyesight returned to him. They then left their country and went to Egypt to meet Yûsuf ‘alayhis salâm. When they came to him, Yûsuf ‘alayhis salâm seated his father and his aunt onto his royal throne. He did this out of respect for them. It was at that time that the two of them and all his brothers fell into prostration before Yûsuf ‘alayhis salâm. In those days, such a prostration in place of salâm was permissible. This is no longer permissible.
A phase of the moon is any of the aspects or appearances presented by the moon as seen from earth, determined by the portion of the moon that is visibly illuminated by the sun. The lunar phases vary cylically as the moon orbits the earth and the earth moon system orbits the sun, according to the relative positions of the earth, the moon and the sun. Since the moon appears bright only due to the sun’s reflected light, only half of the moon facing the sun is illuminated.
اللَّهُ الَّذِي خَلَقَ السَّمَوَاتِ وَالأَرْضَ وَأَنزَلَ مِنْ السَّمَاءِ مَاءً فَأَخْرَجَ بِهِ مِنْ الثَّمَرَاتِ رِزْقاً لَكُمْ وَسَخَّرَ لَكُمْ الْفُلْكَ لِتَجْرِيَ فِي الْبَحْرِ بِأَمْرِهِ وَسَخَّرَ لَكُمْ الأَنهَارَ
وَسَخَّرَ لَكُمْ الشَّمْسَ وَالْقَمَرَ دَائِبَيْنِ وَسَخَّرَ لَكُمْ اللَّيْلَ وَالنَّهَارَ
وَآتَاكُمْ مِنْ كُلِّ مَا سَأَلْتُمُوهُ وَإِنْ تَعُدُّوا نِعْمَةَ اللَّهِ لا تُحْصُوهَا إِنَّ الإِنسَانَ لَظَلُومٌ كَفَّارٌ
Allah is the One who created the heavens and the earth and sent down water from the sky, then brought forth with it sustenance for you from the produce, and subjugated for you the ships, so that they may sail in the sea with His command, and subjugated for you the rivers;
The worst major sin is Shirk. It is of two kinds:
a) To hold that Allah has an equal, whereas He has created you, and to worship another with Him, whether it be a stone, tree, sun, moon, prophet, sheikh, star, angel or other. This is the greatest shirk mentioned by Allah, the Most High, the Almighty, says,
“Allah forgiveth not (the sin of) joining other gods with Him; but He forgiveth whom He pleaseth other sins than this; one who joins other gods with Allah hath strayed far, far away (from the right).” (An-Nisa:l16)
