The Promissed Messiah (AS*) has highlighted the purpose of Jalsa Salana as follows:
"The primary purpose of this Convention is to enable every sincere individual to personally experience religious benefits; They may enhance their knowledge and - due to their being blessed and enabled by Allah, The Exalted - their perception [of Allah] may progress. Among its secondary benefits is that this congregational meeting together will promote mutual introduction among all brothers, and it will strengthen the fraternal ties within this Community."
He further states:
"It is essential for all those who can afford to undertake the journey, that they must come to attend this Convention which embodies many blessed objectives. They should disregard minor inconveniences in the cause of Allah and His prophet (peace be upon him.). Allah yields reward to the sincere persons at every step of their way, and no labour and hardship, undertaken in His way, ever goes to waste. I re-emphasize that you must not rank this convention in the same league as other, ordinary, human assemblies. This is a phenomenon that is based purely on the Divine Help, for propagation of Islam."
(Ishtihar December 7, 1892, Majmoo`ah Ishtiharat Vol. I, Page 340-341)
The Promissed Messiah (AS) prays for all participants of this blessed Jalsa - past, present and future - in the following words:
"I pray to God that He be with all those who are coming to attend the Jalsa. May God grant them great rewards, may He show Mercy on them and remove their hardships and sorrows. May He let them have what they desire and raise them on the Day of Resurrection along with those to whom He has shown Mercy and His Grace. O God, O You who are the great Granter, the Benevolent and Merciful, the Remover of hardships, do listen to all these my prayers and grant us victory over our opponents with great glaring signs, for You have the power to do whatever You like. Ameen." (Ishtihar December 7,1892)*AS = [Arabic] Alayhis Salam meaning Peace be on him
