Well lets start it this way: You believe sadaqa (charity) is a good deed? So there is no harm (in fact its good) if you do it everyday. It is even better if you do it thrice a day? In the same way, IF you consider matam a good deed, do it once a wee, everyday, thrice a day. The more the merrier. I tried to explain this with simple logic, instead of using confusingly big Arabic words which most of you don't seem to understand.
Brother
Your simple logic is illogical. You can not compare Sadaqa is mentioned in Qur'an and Hadith. Maatam is not. There are many Ahadith from Prophet SAW which castigates Wailing and beating oneself.
Please study the following:
Fiqh-us Sunnah 4:22
Wailing over the Dead
Wailing refers to mourning in a loud voice and crying in a high pitch, which was prohibited by the Prophet, peace be upon him, . Abu Malik alAsh'ari reported that the Prophet, peace be upon him, said: "Four practices of the pre-Islamic days of Ignorance will continue to be practiced by my ummah: taking pride in one's parentage, giving a person a father other than his own genealogical father, believing that rain is caused by some stars, and wailing over the dead." He further said: "A (professional) mourner, unless she repents before her death, will be raised on the Day of Judgement wearing a garment of tar and an armor of blistering puss." This is narrated by Ahmad and Muslim.
Umm 'Atiyyah reports: "The Messenger of Allah made us pledge that we will not wail over (the dead)" (Bukhari and Muslim). Al-Bazzar has transmitted, through a sound chain of authorities the report that the Prophet, peace be upon him, said: "Two sounds are accursed in this world and in the hereafter: the sound of wind instruments (to celebrate) good fortune, and of moaning aloud when afflicted with a misfortune."
Abu Musa is reported to have said: 'I declare my disavowal of all that Allah's
Messenger disavowed. The Messenger of Allah disavowed publically a woman who mourns loudly, one who shaves her head, and one who tears her clothes in mourning" (Bukhari and Muslim).
Ahmad narrates from Anas that he said: "The Prophet, peace be upon him, made the women pledge, while giving their allegiance to him, not to mourn loudly for the dead. Thereupon they asked him, 'O Messenger of Allah, some women helped us (in mourning our dead) during the pre-Islamic days. Should we (also in return) help them (in mourning their dead) now that we are Muslims? ' He replied: 'There is no such thing in Islam (i. e., helping each other to mourn the dead loudly)'."
Prohibition of lamenting the deceased
Ibn Masud narrated that the Prophet SAW said:
He who beats his face and tears his clothing, lamenting his fate concerning a misfortune, is doing that which was done in the [pre-Islamic] period of ignorance and is not one of us.

Sad bin 'Ubada became sick and the Prophet along with 'Abdur Rahman bin 'Auf, Sad bin Abi Waqqas and 'Abdullah bin Mas'ud visited him to inquire about his health. When he came to him, he found him surrounded by his household and he asked, "Has he died?" They said, "No, O Allah's Apostle." The Prophet wept and when the people saw the weeping of Allah's Apostle (p.b.u.h) they all wept. He said, "Will you listen? Allah does not punish for shedding tears, nor for the grief of the heart but he punishes or bestows His Mercy because of this." He pointed to his tongue and added, "The deceased is punished for the wailing of his relatives over him." 'Umar used to beat with a stick and throw stones and put dust over the faces (of those who used to wail over the dead).
9:322
Narrated Um Atiyya
We gave the Pledge of allegiance to the Prophet and he recited to me the verse (60.12):
“That they will not associate anything in worship with Allah”. And he also prevented us from wailing and lamenting over the dead. A woman from us held her hand out and said, "Such-and-such a woman cried over a dead person belonging to my family and I want to compensate her for that crying." The Prophet did not say anything in reply and she left and returned. None of those women abided by her pledge except Um Sulaim, Um Al-'Ala', and the daughter of Abi Sabra, the wife of Al-Muadh or the daughter of Abi Sabra, and the wife of Mu'adh.

Narrated Hudhayfah
Allah's Messenger (peace be upon him) said, "Recite the Qur'an with the modulations and tones of the Arabs, but avoid the modulations of those who recite love poetry and the modulations of the people of the two Books. After my death people will come who will trill when they recite the Qur'an as is done in singing and wailing, but it will go no farther than their throats, and they and those who are charmed by their performance will be let into error."
