Meelaad un Nabi [Sallal Laahu Alaieh Wa Sallam] is amongst the sacred days for Muslims. According to my understanding it is very crucial for nourishment and treatment of human minds and hearts, Hence it is necessary for Muslims to keep in their sight the Aswa ur Rasool [Sallal Laahu Alaieh Wa Sallam]. In the following three ways they can keep their emotions intact.

1. The first way is of sending Durood and Salaam which is part and parcel of Muslim’s life, they try to find every possible time to send Durood.

2. The second way deals with Gatherings i.e. Muslims should gather in great number and one person out of them [leader] who is fully versed regarding the Life and works of Pride to the worlds (i.e. Prophet [Sallal Laahu Alaieh Wa Sallam] should mention them in detail so that the devotion to follow the way of Prophet  awakens in hearts of Muslims, for this purpose we have also gathered today.

3. The third way is although difficult but still it to be mentioned is very important. It is that Prophet [Sallal Laahu Alaieh Wa Sallam] is remembered in such a way that our hearts (and ways) become Mazhar (signs) of different aspects of Nabuwat the feeling which was there about 1300 years ago due to literal presence of Prophet [Sallal Laahu Alaieh Wa Sallam] the same feeling arises in our hearts too.
