“A’udu billahil-adheem wa wajhi hil-kareem wa sultanihil-qadeem mina-shaytani-rajeem. Allah-humma, iftah li abwaba rahmattk.”
(I seek refuge in Allah the Al-mighty, and in His noble countenance and in His eternal power, from Satan the Rejected. O Allah, open to me the doors of Your mercy.)
“Assalmu ‘alaika, ayyuhan-nabiyya wa rahmatul-lahi wa barakatuhu”
(Peace be on him, O Prophet, and the mercy and blessings of Allah).
There is no harm if you add:
“Allahumma, atihil-waseelata wal-fadeelata wab-‘athul-maqamal-mahmoudal-ladhee wa-adtahu. Allahumma, ajzih ‘an ummatihi afdala-jaza’.”
(O Lord, give him the right (of intercession) and the favour, and raise him to the praiseworthy station which you promised to him. Allah, reward him on behalf of his ummah (people) with the best of rewards.)
Then move a little to the right to stand before the grave of Abu Bakr (may Allah be pleased with him). Greet him and supplicate Allah to bestow His mercy and forgiveness on him. Again move a little to the right to stand before the grave of Umar (may Allah be pleased with him), and greet him and make supplication for him.
“Assalamu ‘alaikum, ahlal-diyar minal-mu’mineen wal-muslimeen, wa inna insha-Allah bikum lahi-qoon. Nasalal-laha lana wa lakumul-‘afiyah.” (Reported by Muslim)
(Peace be on him, O dwellers of this place from among the Believers and the Muslims, and we well insha-Allah join you. We ask Allah for security (from the Fire of Hell) for ourselves and for you)
According to the Shari’ah besides the mosques and other places mentioned above, there are no other mosques or places in Madinah which are to be visited. Therefore, do not burden yourself by visiting places for which there is no reward or for which, in fact, there might be some blame for doing so. And Allah is the source of guidance.
