´Shaddad bin Aws narrated that the Prophet (s.a.w) said:` "The clever person ids the one who subjugates his soul, and works for what is after death. And the incapable is the one who follows his desires and merely hopes in Allah." [He said:] The meaning of his saying: "Who subjugates his soul", is to say the one who reckons with his soul in the world, before he is reckoned with, on the Day of Judgement. It has been related that 'Umar bin Al-Khattäb said: "Reckon with yourselves before you are reckoned with, and prepare for the Greatest Inquisition. The reckoning of the Day of Judgement is only light for the one who reckoned with himself in the world." And, it has been related that Maimun bin Mihran said: "The slave (of Allah) will not be a Taqi until he has reckoned himself, just as he would account for where his business partner got his food and clothing."

´Abu Hurairah (ra) said:` “The Messenger of Allah (ﷺ) used to order that when one of us went to sleep, he should say: ‘O Allah, Lord of the heavens and Lord of the earths, and our Lord, and the Lord of everything, splitter of the seed-grain and date-stone, and Revealer of the Tawrah and the Injil and the Qur’an. I seek refuge in You from the evil of every evil that You are holding by the forelock. You are the First, there is nothing before You, You are the Last, there is nothing after You, and Az-Zahir, there is nothing above you, and Al-Batin, there is nothing below You. Relieve me of my debt, and enrich me from poverty (Allāhumma rabbas-samāwati wa rabbal-arḍīna wa rabbanā, wa rabba kulli shai’in, fāliqal-ḥabbi wan-nawā, wa munzilat-Tawrāti wal-Injīli wal-Qur’ān. A`ūdhu bika sharri kulli dhi sharrin anta ākhidhun bināṣiyatihi, antal-Awwalu falaisa qablaka shai’un, wa antal-Ākhiru falaisa ba`daka shai’un, waẓ-Ẓāhiru falaisa fauqaka shai'un wal-Bātinu falaisa dūnaka shai’un, iqḍi `annid-daina wa aghninī minal-faqr).’”
