Dua after seeing - first night moon رأى الهلال | Ahlul Bayt Duas and Supplications

اَللّـهُمَّ اَهِلَّهُ عَلَيْنا بِالاَْمْنِ وَالاْيمانِ وَالسَّلامَةِ وَالاِْسْلامِ رَبّي وَرَبُّكَ اللهُ عَزَّوَجَلَّ
اَللّـهُمَّ بارِكْ لَنا في رَجَب وَشَعْبانَ، وبَلِّغْنا شَهْرَ رَمَضانَ، واَعِنّا عَلَى الصِّيامِ وَالْقِيامِ وَحِفْظِ اللِّسانِ، وَغَضِّ الْبَصَرِ، وَلا تَجْعَلْ حَظَّنا مِنْهُ الْجُوعَ وَالْعَطَشَ


After seeing the first night moon the Holy Prophet (s.a.) used to recite the following:
O my Allah pour out much blessings for us in Rajab and Shaban, make us reach safely Ramzan, and take up abstinence and uprightness (fasting and prayers), careful in our speech, turning the eyes from ugliness (the unlawful); and do not let us hunger for food and thirst for water while we observe fast
O` Allah ! make the new moon appear, for us with security. Eeman, safety and Islam. (O`moon) my Lord and Your Lord is Allah the Mighty and Grand.
O` Allah! Send Your Blessings on Mohammad and his Progeny, Ameen.
