WE HAVE ALREADY discussed what one should say when dressing, leaving the house, entering and leaving the lavatory; when performing ablution, going to the mosque, reaching the door and entering it; when hearing the mu’adhdhin and the muqīm; what to say between the adhān and iqāmah; what to say when intending to stand up for ṣalāh; and what to say in ṣalāh from beginning to end; and what to say after it. These are the same for all of the ṣalawāt.
It is mustaḥabb to perform dhikr and other acts of worship in abundance after the sun has passed its zenith.
We relate in the book of at-Tirmidhī from ‘Abdullāh ibn as-Sā’ib 
, who reported that the Messenger of Allah 
used to perform four rak‘ahs after midday before Ẓuhr, and that he said: “It is the hour in which the doors of the heavens are opened, so I like good deeds to ascend for me during it.” [1].At-Tirmidhī described this as a ḥasan hadith.

That is the general meaning of the saying of Allah: “And celebrate the praises of your Lord in the evening and in the morning.” [2].
Wa sabbiḥ bi-ḥamdi Rabbika bi-l-‘ashiyyi wa-l-ibkār.
Linguists say that al-‘ashiyy (‘the evening’) denotes the time between midday and the setting of the sun. Imam Abū Manṣūr al-Azhārī [3].said: “Evening (al-‘ashiyy), according to the Arabs, is the time from when the sun passes its zenith until it sets.”
