إِذْ قَالَ لِقَوْمِهِ أَلاَ تَتَّقُونَ

(When he said to his people: "Will you not have Taqwa") means, `do you not fear Allah when you worship others instead of Him'

أَتَدْعُونَ بَعْلاً وَتَذَرُونَ أَحْسَنَ الْخَـلِقِينَ

The word: إِلْ يَاسِينَ (il ya sin) used in: سَلَامٌ عَلَىٰ إِلْ يَاسِينَ (Salam on it ya sin -130) is also the very name of Sayyidna Ilyas (علیہ السلام) . The people of Arabia are used to adding the letters 'ya' and 'nun' with non-Arab names fairly often - for example, (sina: Sinai) could take the form of سِینِین (sinin). Similarly, here too, two letters have been added.
