You want some real advice? Post on the Bodybuilding Forums.
If you want to add mass, make sure it is lean... i.e do not eat more than 200/500 above your metabolic needs. Calculate your needs by doing a quick google search. This might seem common sense, that your body has a limit on what nutrients are used to rebuild muscle - but I've had friends on diets of 4k calories that burn 2.5k because they believed the extra 1.5k were all going into their muscles. Nope.
You can't really do much during Ramadan as you need to keep hydrated for optimal gain but if you did want a routine there are many you can do with just Dumbbells, be sure not to purchase the vinyl (crap plastic) ones and only the cast iron sets (last forever).
Google for "dumbbell only programmes" , plenty of excercises e.g Dumbell Rows, Bench Presses w/ DBs, Hammer Curls, Lat Raises, Front Raises, Concentrated Curls, Incline Curls, DB Pull Overs, and you would probably want to do this an hour or two after you eat.
Nobody in the world recommends you do strength-building excercises on a fast, this is because if you decide to do some strength training on no food basis you will become weaker as you won't be able to rebuild without nutrients. Light strength hr/2 before iftaar isn't problem, excercising afterwards is more than recommended.
Pretty much gains are stopped for muslims throughout the holy month. Most likely you will gain higher BF through Ramdan.
Also when you do start follow a a 5x5 (i.e ICF) programme for 1-3 months and then afterwards a high volume (i.e low weigh 4x10 w/drop x3) for the same period to see which works best for you. Theres a lot of bro science and utter crap out there so filter through that by reading up. Only productive muscle-related thing you can actually do in Ramadan is read up and educate yourself on proper form etc.
