Once a true connection with Allah comes about; thereupon peace is attained. Thereafter even if something is spoken, it is only done within one's heart and that too with the One who is the Lord of our Hearts! Hence, even if sadness was expressed it was done so only with Him; thus becoming a matter above and beyond creations. So if one is blessed with a connection with Allah; thereupon a bond is formed and the matter goes beyond that of interacting with the creations. Accordingly, what is the purpose of this "Rabta" (connection)?
“لَوْلَا أَن رَّبَطْنَا عَلَى قَلْبِهَا لِتَكُونَ مِنَ الْمُؤْمِنِينَ ...”
Waasbaha fuadu ommi moosa farighan in kadat latubdee bihi lawla an rabatna AAala qalbiha litakoona mina almumineena
… We Connected with her heart so that she continues to have Yaqeen-e-Kaamil (absolute unwavering conviction of belief); i.e. be of the momineen (true believers).
She should be of those with perfect unwavering Faith. What is Eemaan? It is Eemaan-e-Kaamil (absolute unwavering conviction of Belief) – it is Haq-ul-Yaqeen (Belief attained through personal experience); This is what Eemaan is! Yaqeen (Belief or Faith) too; Just like knowledge, has levels. Ilm-ul-Yaqeen (Belief acquired through knowledge), Ain-ul-Yaqeen (Faith acquired through the senses), Haq-ul-Yaqeen (Belief attained through personal experience). All of these are levels of Faith/Belief. Ilm-ul-Yaqeen (Belief acquired through knowledge); e.g. we see smoke rising from a spot, we instantly believe that there is fire there; as smoke does not emit without fire. either flames are blazing or something is still smouldering. Fire is there; thereupon smoke will be there. The smoke is evidence of fire; thus we gain knowledge of the fire. This is "ilm-ul-Yaqeen". Similarly, we heard from our elders (wise-men), that there is an Allah and His Rasuls (Messengers); hence we accepted it. This too is Ilm-ul-Yaqeen (Belief derived through knowledge). Ain-ul-Yaqeen (Belief acquired through the senses) is when we go there ourselves, and witness for ourselves that the fire is burning and the smoke is rising; This is Ain-ul-Yaqeen. The Ain-ul-Yaqeen of Eemaan is if one attains access to the Court of the Prophet Muhammad (salAllahualaihiwassalam) The pleasure that is attained thereupon, cannot be explained to one who does not have this access. Further beyond this is Haq-ul-Yaqeen (Belief attained through personal experience). Haq-ul-Yaqeen is attained if your clothes caught fire or your hand is touched by the fire thus leaving it burnt. The Belief that is attained thereupon is the highest level of belief and is unfaltering. Likewise, those who receive the loving touch of the Holy Prophet's (salAllahualaihiwassalam) blessed hands; thereby acquainting them of this pleasure; gaining familiarity of those feelings; that is when the Eemaan reaches the level of being Kaamil (perfect/absolutely unwavering).
