س ١٨: ما معنى شهادة: "لا إله إلا الله"؟
Q 18: What does the testimony, "There is no god but Allah" mean?
لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَمَعْنَاهُ أَنَّهُ لَا يَحِقُّ لِأَحَدٍ أَنْ يُعْبَدَ إِلَّا اللهُ الَّذِي لَا شَرِيكَ لَهُ وَلَا نِدَّ لَهُ فِي الْعِبَادَةِ وَلَا فِي الْمُلْكِ. قَالَ اللهُ تَعَالَى:
A ---It means that none has the right to be worshipped but Allah Who has no partners or rivals with Him in Worship or Dominion. Allah the Most High says:
ذٰلِكَ بِأَنَّ اللَّهَ هُوَ الْحَقُّ (الْإِلَهُ الْحَقُّ الَّذِي لَا شَرِيكَ لَهُ وَلَا نِدَّ لَهُ مِنْ بَيْنِ كُلِّ مَا هُوَ مَوْجُودٌ)، وَأَنَّ مَا يَدْعُونَ مِنْ دُونِهِ (أَيِ الْمُشْرِكُونَ) هُوَ الْبَاطِلُ. وَإِنَّ اللَّهَ هُوَ الْعَلِيُّ الْكَبِيرُ. (الحج: 62)
That is because Allah -He is the Truth (the only True God of all that exists, Who has no partners or rivals with Him), and what they (the polytheists) invoke besides Him, it is Balil (falsehood). And verily, Allah - He is the Most High, the Most Great. (Al-Hajj, 62)
