The Dua (supplication) is a “request”, and since Almighty Allah is in charge of the universe and manages all creations, asking Him is direct. Requesting from others, like the Prophets or the Imams, is not permissible if the seeker considers them as being independent in dealing with his request, aside from Almighty Allah. This is like considering a partner with Almighty Allah.
If the believer seeks the intercession of the Prophets and the Imams (peace be upon them) as they can then ask Almighty Allah to fulfill the seeker’s supplication, or he requests from Almighty Allah to fulfill his supplication by referring to the high rank of the noble personalities of the Prophets and the Imams (peace be upon them), then these two kinds of supplications are considered as permissible acts of worship.

There are many Ziyaras taught by the Ahlulbait (peace be upon them), such as al-Ziyarah al-Jami’ah, Ziyarat Warith and Ziyarat-e-Ashura. There are also many supplications, like Du’a Kumayl and the supplications of al-Sahifah al-Sajjadiyah.

We cannot confirm that an Imam has recited this supplication. Yes, it has been reported in some books that the said supplication is narrated from one of the Imams (peace be upon them). Supplicating to Almighty Allah through the Prophet or the Imams (peace be upon them) is amongst the recommended deeds, whether we use this particular supplication or another Dua.

The mentioned supplication is not amongst the supplications that are prescribed to be recited at the mentioned time. There are particular supplications that are specified to be recited in the early morning in the book "Mafateeh al-Jinan".

Dua al-Adeelah which is mentioned in the supplications books is not related to an Imam. It is recommended to recognize the true beliefs when one is dying, and at all times, whether this done by reciting Dua al-Adeelah or using other ways to strengthen the true belief in one’s soul and defeat the attacks of Satan and his mischief.

This specific text is not amongst the supplications that have been narrated from the Infallibles (peace be upon them). However, it is permissible to recite it in order to seek intercession from Imam Ali bin Abi Talib, for the fulfilment of one’s needs and wishes. All matters are in God’s power, but he made the Prophet and his progeny (peace be upon them) intercessors.

Repeatedly seeking forgiveness is one of the causes of getting sustenance, if God wishes. Almighty Allah said: “Seek the pardon of your Lord. Lo! He was ever forgiving. He will let loose the sky for you in plenteous rain” (71:10-11).

Seek forgiveness from Almighty Allah and invoking His blessings upon the Prophet and his household (peace be upon them) – “Istighfar” and reciting the "Salawat" – repeatedly are amongst the acts that may cause the duas to be accepted and answered.

It has been reported in some narrations that repeatedly reciting Surah Al- Qadr (chapter 97 of the Holy Quran) and repeatedly seeking forgiveness increases sustenance and the means of sustenance.

It has been narrated from the Imams (peace be upon them) that reciting the last two chapters of the Holy Quran (chapters 113 and 114) helps to protect from the evil eye.

There is no dua for wishing to die. It is not amongst the characters of a believer to wish to die, nor to ask his Lord for such an issue. Rather, a believer is expected to call Almighty Allah to remove the hardship and decrease its effect on him, as He is All-Merciful.

There is no specific supplication for this that has been narrated from the Infallibles (peace be upon them). However, it has been reported that to fulfill one's need, one can prostrate and say seven time "Ya Arham al-Rahimeen", then ask for your wish.

Yes, it is permissible, but it is better if the payment is given and taken as a gift.

You can pray for their guidance, and you can also accept their gifts. Religious narrations encourage good behavior with the unbelievers.

What has been mentioned on the website is the dislike of wiping the face specifically after Qunoot, not after other various kinds of supplications (du’as). It is recommended to wipe the face after every Du’a, except for the Qunoot as it is disliked. As for wiping the face after the prayer, we are not aware of a narration that encourages or discourages such an act.

Yes, it is permissible, and it is permissible to do so in any language.

The effect of greater sustenance and the like from the supplication that the Imam (peace be upon him) taught shall occur with the permission of Almighty Allah. Other supplications are general invocations to Almighty Allah and are good at all occasions and times.

We should always ask Almighty Allah and seek His blessings and hope for His answer, as this feeling is one of the reasons to grant the wishes. If we do not get the request answered, we stay in this condition as we are gaining the reward of the supplications, even if we did not obtain what we are asking for.
If we do not get what we wanted, we accept what Almighty Allah's wills, since He indeed knows the best for us. With this submission to what He wants, we gain the great reward that Almighty Allah kept for whoever accepts His will as He is the Most Merciful.

There is no specific time period for waiting for the response to one’s supplication. But, if the believer insists on asking and seeking, then such supplications are closer to be answered.

The dua (supplication) is asking Almighty Allah. The Imams of the Ahlulbait are intercessors to Allah and He does not reject their intercession. Nothing is wrong in seeking intercession from the Prophet and his household (peace be upon them). It is mentioned in the Holy Quran: “And if, when they had wronged themselves, they had but come unto thee and asked forgiveness of Allah, and asked forgiveness of the Messenger, they would have found Allah Forgiving, Merciful.” (4:64)
