Out of love, appreciation, gratitude or other related noble feelings, a Muslim is encouraged to utter certain phrases at the mention of Allaah, His messengers, the sahaabah (Messenger's companions), or other righteous Muslims. For printing and space reasons, instead of presenting the complete phrase, a condensed Arabic statement is provided in some cases, and a mnemonic is employed in others, as follows:
(SWT) Subhaanahu wa ta`aalaa: a phrase uttered at the mention of Allaah, meaning, "He is exalted above all weakness or indignity".
Salla 'Llaahu `alayhi wa sallam: a phrase uttered at the mention of Muhammad or other messengers, meaning, "May Allaah's peace and praise be on him".
() Radiya 'Llaahu `anhu: a phrase uttered at the mention of one of the male sahaabah meaning, "May Allaah be pleased with him".
() Raiya 'Llaahu `anhum: a phrase uttered at the mention of three or more of the male sahaabah meaning, "May Allaah be pleased with them".
() Raiya 'Llaahu `anhaa: a mnemonic of "May Allaah be pleased with her" or the plural thereof. This is uttered at the mention of one or more of the female Sahaabah.
(r) Raimahu 'Llaah: a mnemonic of "May Allaah have mercy on him" or the feminine or plural thereof. It is said at the mention of past `ulamaa' and pious Muslims other than the Sahaabah.
When coming across any of these symbols, the reader is advised to utter the complete phrase in order to obtain the reward of saying the appropriate Thikr (remembrance) or Du`aa' (invocation).
