Seeking Allaah’ forgiveness after the last tashahhud and before salam
Allaahum-maghfir lee maa qaddamatu, wa maa ‘akhkhartu, wa maa ‘asrartu, wa maa a’lantu, wa maa ‘asraftu, wa maa ‘Anta a’lamu bihi minnee. ‘Antal-Muqaddimu (The One Who brings forward) wa ‘Antal-Mu’akhkhiru (The One Who puts back) laa ‘ilaaha ‘illaa Anta.
“O Allah, forgive me for those sins which have come to pass as well as those which shall come to pass, and those I have committed in secret as well as those I have made public, and where I have exceeded all bounds as well as those things about which You are more knowledgeable. You are Al-Muqaddim and Al-Mu-akhkhir. None has the right to be worshipped except You.”
Note : al-Muqaddim (The One Who brings forward) , al-Mu’akhkhir (The One Who puts back) are the two names of Allaah
Making Dua (supplication) in Sujood (prostration) that Allaah teaches you the Qur’an
Shaykh Abdur-Rahman al-Ajlaan
Shaykh Abdur-Rahman al-Ajlaan – الشيخ عبد الرحمن العجلان
Is it correct for me to make Dua (supplication) to Allaah (Azza wa Jal) while I am prostrating that He teaches me the Noble Qur’an?
Yes, O my brother.
Ask Allaah while you are prostrating for what you would love from the goodness of this world and the next world.
As for memorising the Qur’an then this is from the goodness of the next world. It is something by which the good deeds will be increased.
So, ask Allaah for this because the Prophet (peace and blessings be upon him) said, “As for the bowing then glorify the Lord in it, as for the prostration do a lot of praying in it because it is being worthy of answered for you, meaning it is suitable that it will be answered for you.
And the Prophet (Peace and blessings be upon him) said, “The closest the slave is to his Lord is when he is prostrating.”
So, make Dua a lot, ask Allaah for what you would love, from the goodness of this world and the next world.

O Allah, place light in my heart, and on my tongue light, and in my ears light and in my sight light, and above me light, and below me light, and to my right light, and to my left light, and before me light and behind me light. Place in my soul light. Magnify for me light, and amplify for me light. Make for me light, and make me light. O Allaah, grant me light, and place light in my nerves, and in my body light and in my blood light and in my hair light and in my skin light.
[O Allaah, make for me a light in my grave… and a light in my bones.]  [Increase me in light, increase me in light, increase me in light.]  [Grant me light upon light] 
 Up to this point was reported by Al-Bukhaari 11/116 (Hadith no. 6316) and by Muslim 1/526, 529-530 (Hadith no. 763)  At-Tirmidhi 5/483 (Hadith no. 3419)  Al-Bukhaari in Al-‘Adaab Al-Mufrad (Hadith no. 695), p. 258. See also Al-Albaani, Sahih Al-‘Adab Al-Mufrad (no. 536)  Al-Bukhaari, cf. Al-Asqalaani, Fathul-Baari 11/118
It is one of the Supplications Prophet (Peace be upon him) used to supplicate in Sujood
«O Allaah! Place light in my heart; [and light in my tongue;] and place light in my hearing; and place light in my seeing; and place light from below me; and place light from above me, and light on my right, and light on my left; and place light ahead of me; and place light behind me; [and place light in my self;] and make the light greater for me»

The majority of scholars held the view that this Du`a’ (supplication) falls under the category of stressed Sunnah. It was been reported on the authority of Tawus, one of the great Tabi`un (Followers, the generation after the Companions of the Prophet) that this Du`a’ is obligatory. Tawus is also reported to have ordered his son to repeat his Salah when he knew that he did not recite this Du`a’. This indicates that such Du`a’ is a stressed Sunnah, which the Mu’min should not miss in obligatory or voluntary Salah.
People are subject to trials in their lives and after death. One may commit sins or Bid`ah (innovation in Islam), or be exposed to Kufr (disbelief) in Allah’s Religion. One might be tempted with wealth, lusts, sins, or evil company, and commit acts which displease Allah, whether it be Kufr, Bid`ah, or sins during their lives or at their death. We ask Allah to grant us protection from it. One may be tested with the trial of Al-Masih-ul-Dajjal if they live during the time when he appears. Al-Masih-ul-Dajjal will appear at the end of time, claiming to be a prophet and lord of all creation. Many people will follow him. We seek refuge with Allah from this. They will be doomed because of their following him. One should ask the Lord to protect them from these trials, because they do not know whether they will be saved or not. Therefore, one must ask Allah to protect them from the torment of Hellfire, the punishment of the grave, the trials of life and death and the trial of Al-Masih-ul-Dajjal. Everyone is in need of this Du`a’ so that they will not be tried in their life or upon dying; and so that they will not experience the trial of Al-Masih-ul-Dajjal if they happen to live at the time when he appears. We ask Allah to save us from this.
