Is the following article about Aashouraa authentic?

Question

Assalaamu alaikum. Is the following article authentic? Jazakumul khair It is thus recommended to do an utmost of ibaadats during this blessed day and also during its night (Laÿlat-ul-‘Aashourah), to make charity and to observe the roza (fast) during this blessed day. Hazrat Hafsah (r.a) reports that the holy prophet was regularly fasting on the day of the `Aashourah. It should be noted that at the beginning of Islam the roza of Yawm-e-`Aashourah was formerly compulsory, but upon the last ummah (people), when the roza of Ramadwaan became faraz (compulsory), the roza of Yawm-e-`Aashourah becomes a significant nafil (surplus) According to a hadeeth of Muslim shareef, Hazrat Abdullah Ibne Abbaas (r.a) reports that when the holy prophet observed the roza of Yawm-e-`Aashourah, he also advised the sahabas to make the same way. Some sahabas told him that the Jews also was respecting and observed this roza of `Aashourah and so the beloved prophet replied that if he would be still alive the following year, he would also observe the day before, i.e. the 9th day of Muharram too. But the holy prophet did intiqaal (deceased) the following year, but since the sahabas, taabi’eens and awliyaas who followed all kept this principle by observing the roza the two days altogether, i.e. 9th and the 10th of Muharram. However, it should be noted that if somebody does not have the occasion to observe the roza the 9th day, he can observe only the 10th day, i.e. Yawm-e-`Aashourah only (except if it happen to be a Friday, so, it will be necessary for him to add another day, therefore the saturday also). According to a hadeeth of Mishkaat shareef, Hazrat Abdullah Ibne Mas’ood (r.a) reported that the beloved prophet said that the muslims who offer Swadaqa on the blessed day of `Aashourah, only for the pleasure of Allah ta’ala, on his turn Allah makes the promise that he will grant these people blessings (barakats) in their food (rozi) during one whole year.Hazrat Jaabir (r.a) and Hazrat U’ayna (r.a) specified that during 50 to 60 years they practised the recommendation of this hadeeth, by observing the roza, nafil namazs and the swadaqa on the day of `Aashourah and could witness how Allah increased their rozi and they thus recommended to all muslims to do the same. Hazrat Ali (r.a) said that on the day of `Aashourah, cut your nails, take a special bath, put the surma (black eyes) and the perfume (attar), observe the roza, make the namazs nafils, offer the swadaqa, make the tilaawat (reading) of Qur’aan shareef, make Istighfaar (asking allah for forgiveness), make zikrr etc… Allah appreciate very much these ibaadats from us. Upon the arrival of the night of `Aashourah (Laylat-ul-`Aashourah/Shabbe-`Aashourah), Hazrat Abdullah Ibne `Abbaas (r.a) recommended to make 4 raka’ats of namaz nafils as follows: in each raka’at, after sourah al-Faatihah, read 1 time Aayat-ul-kursiy and 3 times sourah al-Ikhlaas. After the salaam, read 100 times the 3rd kalimah. This ibaadat purifies believer from his sins, raises his faith (imaan) and attracts on him the blessings (barkats) of Allah ta’ala. During the day of the `Aashourah, at the time of Tchaast (between 9 o’clock and 11 o’clock of the morning), read 2 raka’ats of namaz nafil with the niyyat of Swalaat-ul-`Aashourah and in each raka’at, after sourah al-Faatihah, read 10 times sourah al-Ikhlaas. After the salaam, read 1 time Aayat-ul-kursiy and 9 times Daroud-e-Ibraheem and then 70 times : “Hasbiyallaahu wa ni’mal wakeel, ni’mal mawlaa wa ni’man-nasweerr”. After that, make your du’as, insha-Allah they will be accepted. Aameen.
