why afraid of bid'ah

Has told me: Muhammad ibn Abdallah ibn Numair said: has told me of the father of Hisham RHA Aisha: that the man came to the Prophet and said: O Messenger of Allah, my mother had died and no berwasiyat, and I thought if she spoke, then he will give alms . Is it going to reward it if I give charity? He replied "Na'am" (yes).
Annawawi said: In this hadeeth that the charity on behalf of the dead was beneficial to him and reward to him, so this is Ijma 'Ulama' (the consensus of the scholars '), and Ulama' also agreed arriving prayers to dead, and the settlement of debts , based on the texts that terwarid, and the shah also Hajj on behalf of the dead if the Islam Hajj is the pilgrimage (Hajj compulsory), and likewise the Sunnah Hajj shah when the dead intestate, so this most shah opinions in our opinion.
And scholars disagree on the merit of fasting arriving when the dead die in a state of fasting have dependents, then the opinion that it Rajih due jawaz ahaadeeth shohih.
And the famous opinion in our schools, that the Quran is read until the reward is not dead, and said a group of Ashabuna (Madzhab scholars Shafi'i) that the reward to the dead, and Imam Ahmad bin Hanbal also said that ( reward to the dead).
As for the reward and the reward of prayer ketho'atan any reward, then we consider not to think so too jumhur Ulama (Ulama majority), and Imam Ahmad said: All That reward to the dead as the hajj.

(Shohih Muslim Bisyarhi Annawawi, Chapter Wushulu Anil Tsawabisshodaqoh ilayhi dead, Vol 4 p. 90 cet Dar Al Fikr),

As a result, a mistake of not reading or got to reward the Qur'an to the dead is a classic problem that has always existed, but in history they did not have a different opinion that was most true and misleading others.

The one that feels most right when accusing others astray. If you read the Qur'an meyaqini reward until the dead, so please read, even if it was not until, you can still reward, because reciting the Holy Qur'an it is in sunnahkan.
If you do not got to reward meyaqini reading the Holy Qur'an to the dead, so do not read and do not mislead the meyaqini got to reading the Qur'an.


But kesimpulanya, give charity on behalf of the dead were dead rewards UNTIL TO! That is the agreement of the Ulama.

The Prophet SAW said "Every interpretation that shodaqoh, and that Tahmid shodaqoh Each and Every Tahlil it shodaqoh (Reported by Muslim Hadith No. 1674)

when Takbir, Tahmid, and Tahlil in anggapa shodaqoh, then the reward of reading it can reach the dead.
As a result, Tahlilan Seven days of death is manivestasi / implementation of these opinions, as in fatwakan Imam Jalaluddin al Assuyuthi:
Imam Ahmad ibn Hanbal in which azzuhd book dinuqil by Imam Jalaluddin Assuyuthi "Imam Ahmad said: It has told me Hashim bin Al Qasim Al 'Asyja'i from Sufyan said: Thawwus Alyamany (Tabi'in the study to more than 70 companions of the Prophet SAW ) said: "Those exposed to libel the dead in his grave for seven days, and they really like it if on the days that his family charity bestow upon them. (Alhawi Lilfatawa juz 178 p. 2).
This is why the followers of the basic schools of Shafi'i do shodaqoh 7-day mortality in Java called tahlilan / safety. It is wrong that does not respect differences of opinion and accusing others astray. And Allaah knows best.
