Going to Masjid an-Nabawi
Step into Masjid an-Nabawi with your right foot and recite the du'a for entering a Masjid:
أَعوذُ باللهِ العَظيـم وَبِوَجْهِـهِ الكَرِيـم وَسُلْطـانِه القَديـم مِنَ الشّيْـطانِ الرَّجـيم،[ بِسْـمِ الله، وَالصَّلاةُ وَالسَّلامُ عَلى رَسولِ الله]، اللّهُـمَّ افْتَـحْ لي أَبْوابَ رَحْمَتـِك
Then pray two rakahs of entering a masjid.
There is an area in Masjid an-Nabawi known as Riyadh ul-Jannah, about which the Prophet ﷺ said:
“One of the gardens of Jannah lies between my house and the pulpit”
