“Verily! We have sent it (Qur-aan) down in the Night of Decree (Laylatul-Qadr). And what will make you know what the Night of Decree is? The Night of Decree is better than a thousand months. Therein descend the angels and the Rooh (i.e. Gabriel) by Allaah’s Permission with all Decrees, Peace! until the appearance of dawn.” (Surah 97/al-Qadr, v:1-5)
Sayyidah ‘Aa-ishah (RadiyAllaahu ‘anhaa) narrated, “Allah’s Messenger (Sallallaahu ‘Alayhi wa Sallam) used to practice I’tikaaf in the last ten nights and say: ‘Seek out Laylatul-Qadr in the (odd nights) of the last ten days of Ramadaan.” [Bukhari, Muslim]
It is prescribed to supplicate a great in Laylatul Qadr. It is reported from ‘Aa-ishah (RadiyAllaahu ‘anhaa): “O Messenger of Allah! What if I knew which night Lailatul-Qadr was, then what should I say in it?” He said: “Say: Allaahumma innaka ‘affuwwun tuhibbul ‘afwa fa’fu ‘annee.” (O Allah, You are forgiving and You love forgiveness, so forgive me).” [Tirmidhi]
If some one is too weak and unable to pray for all odd nights, then he must not let go the last seven nights. It is reported from Ibn Umar (RadiyAllaahu ‘anhu) that Allah’s Messenger (Sallallaahu ‘Alayhi wa Sallam) said: “Seek it in the last ten, and if one of you is too weak or unable then let him not allow that to make him miss the final seven.” (Bukhari, Muslim)
Rasoolullaah (Sallallaahu ‘Alayhi wa Sallam) used to stay up and pray on Laylatul-Qadr so it is prescribed to stay up and pray whole night. He (Sallallaahu ‘Alayhi wa Sallam) said: “Whoever stands in (Prayer) in Laylatul-Qadr out of Eemaan and seeking reward then his previous sins are forgiven.” [Bukhari]
One should strive hard in worship during the last ten days of Ramadaan. Rasoolullaah (Sallallaahu ‘Alayhi wa Sallam) used to worship in the last ten days of Ramadaan as he never did at any other time. One should pray, read Qur-aan and make Du‘a. it is reported from ‘Aa-ishah (RadiyAllaahu ‘anhaa): “The Prophet (Sallallaahu ‘Alayhi wa Sallam) used to exert himself in the last ten nights more than he would at other times.” [Muslim] If one misses this blessed night it is as if he has missed a lot. Therefore every Muslim should pray and hope for the great reward associated with this night.
