assalaamu alaykum brother
these are the basic prayers that a muslim is mean't to recite when breaking there fast:
Allaahumma 'innee 'as'aluka birahmatikal-latee wasi'at kulla shay 'in'an taghfira lee
O Allah i ask you by your mercy,which encompasses all things, that you forgive me.
just before eating you can also say:
Allaahumma baarik lanaafeehi wa 'at'imnaa khayranminhu
O Allah,bless us in it and provide us with better than it.
After eating:
Alhamdu lillaahil-lathee 'at'amanee haathaa, wa razaqaneehi,min ghayri hawlin minnee wa laa quwwatin
praise be to Allah who has given me this food and sustained me with it though i was unable to doit and powerless.
these invocations are compulsory for a blessful ramadhan:statisfie
of course along with your 5times pray also.
Wishing you 1month of ramadhan
4weeks of barkat
30days of forgiveness
720hours of guidance
43200minutes of purity
2592000seconds of noor....! please remember me in your duas.
take care
