Dhikr: keeping God's name present
Dhikr means the name stays in a person's mouth and mind until it runs on its own. Handling sacred work every day can wear a name smooth, so it gets used the way a cashier says have a nice day. Al-Ghazali compares repeating the name to polishing a mirror; the polishing comes from attention, which anyone can bring, expert or not.
Wherever you turn, there is the face of God: no place is off the map
A line from the Quran that Sufis come back to constantly. Someone who guards a holy site slowly starts to feel that access runs through their hands, and their own sloppiness stops seeming serious. The line removes that ownership, since God is already being met in places nobody signed off on, and the guardian turns out to be one worshipper among millions.
Ilāh al-muʿtaqad: the God each person pictures
Ibn Arabi's name for the God a believer forms out of their own understanding. From inside one tradition, the worship of outsiders looks like noise, and it feels obvious that only the home version lands. Ibn Arabi warns against locking onto a single picture and calling every other picture false, because the God standing behind all of them is bigger than any one of them.
Neither the flesh nor the blood reaches God, only your care does: the heart is what arrives
A Quranic line about animal sacrifice, saying the meat itself never gets there. A person can complete every required step, hand over the goods, and feel the account settled while nothing has moved inside them. The condition of the one carrying the gift is what travels, so a small offering brought with love weighs more than a costly one brought grudgingly.
Ikhlāṣ: sincerity, the act done for God alone
Ikhlāṣ means nothing else is mixed into the motive. Worship kept up for a salary, a reputation, or plain habit holds its shape perfectly while emptying out, and the giver quietly keeps the good things back and hands over what was headed for the bin anyway. Al-Ghazali treats sincerity as the thing that decides whether an act counts at all, so two identical gifts can be worth wildly different amounts depending on what the giver wanted in return.
