Please remember that all of these are duaa (i.e. supplications), and supplications are a form of worship. And it is not at all permissible to abbreviate acts of worship however you wish.
The habit of the Salaf and those who came after them was to write these out fully and unabbreviated - even if it was repeated many times on the same line - as opposed to the absurd practice of our times, writing them out as “SWT”, “SAWS”, “PBUH”, “RA”, etc…
When you abbreviate them into initials, they cease being supplications and at the same time, it detracts from the right which Allaah, His Prophet, the Companions and the Salaf have upon us.
We owe it to them to send proper supplications upon them. So let us not be so lazy and stingy, my brothers and sisters!
