Worship Allaah & do not associate anything with Him
Allaah Ta’ala said:
(۞ وَٱعۡبُدُوا۟ ٱللَّهَ وَلَا تُشۡرِكُوا۟ بِهِۦ شَيْئًا وَبِٱلۡوَ ٰلِدَیۡنِ إِحۡسنࣰا وَبِذِی ٱلۡقُرۡبَىٰ وَٱلۡیَتَامَىٰ وَٱلۡمَسَاكِینِ
《Worship Allah and join none with Him in worship, and do good to parents, kinsfolk, orphans, Al-Masakin (the poor),》
Surah Nisa: 36
