In a narration of Tirmidhi, Rasulullah (sallallaahu alayhi wa sallam) is reported to have said, 'He who performs Fajr Salat with Jamaat and remains seated in the same place while engaging in Dhikr until after sunrise and thereafter performs 2 Rakaats Nafil Salat, (Ishraaq), he will obtain the Thawaab of one Hajj and one Umrah.' (Tirmidhi).
I think one thing holding most people back from doing the daily masnoon ad'iaah and adhkaar in the morning and in the evening is the fact that they believe they will get too tired to perform the rest of their daily tasks. For most people it is quite a task to stay up until ishraaq and pray two short raka'ahs. But with the coming of summer, that excuse is no longer valid anymore. So insha'Allah, brothers should try their hardest and make it to the masjid for fajr salaah and after prayer is over, pick up Hisn-ul-Muslim or anyother book of adhkaar (Munaajaat-e-Maqbool of Maulana Ashraf Ali Thanwi is pretty long, one can read from there too otherwise) and moisten his tongue with the dhikr of Allah (sisters can do the same at home). By the time one is finished with the chapter, it will be close to ishraaq and one can read surah YaaSeen and by the time he/she is finished, they can simply stand up, offer their two raka'ahs, and as simple as that one has obtained the reward of one Hajj and one Umrah. Allahu Akbar.
The adhkaar for morning and evening from Hisn-ul-Muslim can be viewed here:
After practicing this for a week or so, it becomes quite simple to memorize them. Insha'Allah, thereafter one can ask Allah for steadfastness in this and as summer passes them by, they will insha'Allah still be practicing this blessed action.
And Wallahi, these adhkaar are so beautiful and so powerful, one's day seem incomplete on those days where one does not have the opportunity to recite them. Just like Shaykh ibn Taymiyyah was quoted as saying from his student ibn ul-Qayyim, that he had to spend an hour or so in the morning doing adhkaar as it was his nourishment.
May Allah (subhaanahu wa ta'aalaa) allow us to implement this sunnah and ALL other sunan into our lives, as this is the TRUE respect and love of the status of Sayyidunaa Muhammad (sallallaahu alayhi wa sallam).
