2. Late at night

When people are sleeping and busy with worldly pleasures Allah (SWT) gives the believers an opportunity, or an answer hour if they can fight sleep and invoke Allah (SWT) for whatever they need.

3. Between Adhan and Iqama <O:P></O:P>

Anas (Ra) narrated that Allah’s  Messenger (SAW) said: “A supplication made between the Adhan and Iqama is not rejected.”   (An-Nasai and Ibn Hibban graded it sahih (sound))

4. An Hour On Friday<O:P> </O:P>

 Narrated Abu Huraira (ra): Allah’s  Messenger (SAW) talked about Friday and said: “There is an hour on Friday and if a Muslim gets it while offering Salat (prayer) and asks something from Allah (Subhanahu wa Ta'ala), then Allah (Subhanahu wa Ta'ala) will definitely meet his demand.”   And he (the Prophet (SAW) pointed out the shortness of that time with his hands.  (Bukhari)

Some said this hour is from the time the Imam (prayer’s  leader) enters the mosque on Friday’s  prayer until the prayer is over where others have said that it is the last hour of the day. (Note: when we say an hour here we do not mean the hour everyone knows  (60 minutes) but an unspecified period of time because the time counters which we use today came after the Prophet (SAW) had died

5. While Drinking Zamzam Water

Jaber (Ra) narrated that Allah’s  Messenger (SAW) said:  “Zamzam water is for what it is drunk for.”  (Ahmed and Ibn Majah)

This means that when you drink Zamzam water you may ask Allah (Subhanahu wa Ta'ala) for anything you like to gain or benefit from this water such as healing from illness.... etc.

6. While Prostrating <O:P></O:P>

Abu Huraira (Ra) narrated that Allah’s  Messenger (SAW), said:  “The nearest a slave can be to his Rabb (Cherisher and Sustainer) is when he is prostrating, so invoke (supplicate) Allah (Subhanahu wa Ta'ala) much.  (Muslim) When a Muslim is in his Salat (prayer) he is facing Allah (Subhanahu wa Ta'ala) and when he prostrates he is the nearest he can be to Allah (Subhanahu wa Ta'ala) so it is best to invoke Allah (SWT) at this time.

On The Day Of Arafa: The Messenger of Allah (SAW) said: The best supplication is the supplication on the day of Arafa.  (At-Tirmidhi and Malik)

7. When Waking Up at Night

Narrated Ubada Bin As-Samit that Allah’s  Messenger (SAW) said: “Whomever wakes up at night and says La ilaha illallahu wahdahu la shrika lahu lahulmulku, wa lahul hamdu, wa huwa ala kulli shai'in qadir. Alhamdu lillahi, wa subhanallahi wa la ilaha illallahu, wallah akbir, wa la hawla wala quwata illa billah” (none has the right to be worshipped but Allah (Subhanahu wa Ta'ala) He is the only one who has no partners. His is the kingdom and all the praises are for Allah (Subhanahu wa Ta'ala) All the glories are for Allah(SWT) And none has the right to be worshipped but Allah (Subhanahu wa Ta'ala) and Allah(SWT) is the most Great and there is neither might nor power except with Allah (Subhanahu wa Ta'ala) and then says, Allahumma ighfir li (O Allah! Forgive me) or invokes Allah (Subhanahu wa Ta'ala), he will be responded to and if he makes ablution and performs Salat (prayer), his Salat (prayer) will be accepted.  (Bukhari)

8. At The End Of The Obligatory “Salat” : <O:P></O:P>

This time is after saying “At-tahyat” , and before making Tasleem (finishing prayer)

9. The Night Of 'Qadr' (Decree) <O:P></O:P>

Narrated Sahel Ibn Saad (Ra): that the Messenger of Allah (SAW) said: Two will not be rejected, Supplication after the Adhan (call of prayer) and at the time of the rain.  (Al-Hakim and Abu Dawud)

The time of the rain is a time of mercy from Allah (Subhanahu wa Ta'ala) so, one should take advantage of this time when Allah (SWT) is having mercy on His slaves.

11. At the Adhan

12. The One Who Is Suffering Injustice <O:P></O:P>

The Messenger of Allah (SAW) said to Mua'ad Ibn Jabal (Ra), Beware of the supplication of the unjustly treated, because there is no shelter or veil between it (the supplication of the one who is suffering injustice) and Allah (SWT)  (Al-Bukhari and Muslim)

The One who is suffering injustice is heard by Allah (Subhanahu wa Ta'ala) when he invokes Allah (Subhanahu wa Ta'ala) to retain his rights from the unjust one. Allah (Subhanahu wa Ta'ala) has sworn to help the one who is suffering from injustice sooner or later as the Messenger of Allah (SAW) said.

The Messenger of Allah (SAW) said; Three supplications will not be rejected (by Allah  (SWT)), the supplication of the parent for his child, the supplication of the one who is fasting, and the supplication of the traveler,.  [al-Bayhaqi]

During travel supplication is heard by Allah (Subhanahu wa Ta'ala) if the trip is for a good reason, but if the trip is for a bad intention or to perform illegal things (making sins) this will not apply to it.
