“ ‘Ubûdiyyah looks to Ilahî command and Ilahî acceptance. What summons ‘ubûdiyyah is Ilahî command and its result is the acceptance of Haqq. Its fruits and benefits pertain to the âkhirah.” The Seventeenth Flash - Thirteenth Note/The Second Matter
“Ikhlas is the rûh of the ‘ibâdah. Ikhlas in ‘ibâdah is this, that it is performed only because it is commanded, although it comprises numerous instances of hikmah. Each of these may be a real cause (‘illah) for performing ‘ibâdah, but ikhlas makes it imperative that the real cause (‘illah) be the command to perform it. If the hikmah is made to be the real cause (‘illah), the ‘ibâdah is bâtil, but if it merely encourages the person to perform the ‘ibâdah, it is permissible (jâiz).” Signs of Miraculousness ( 163 )
