I want to know authenticity of following Ahadith: 1) Umar (Radiya Allahu Anhu) narrated that Prophet (Sallallahu Alaihi wa Sallam) taught this Du'a: Allahum-maj 'Al-Sarrerati Khayram Min 'Ala Niyati Waj 'al 'Ala Niyati Saliha - Allahumma Inni Asaluka Min Salihi Ma Tu'tin Nasa Min al-Ahli Wal Mali Wal Waladi Gayzidh Dhali Wal al-mudhilli. (At-Tirmidhi) 2) Umm-e-Ma'bad (Radiya Allahu Anha) narrated that she heard Prophet (Sallallahu Alaihi wa Sallam) making this Du'a: 'Allahumma Tahhir Qalbi Minan Nifaqi Wa 'Amali Min ar-Riyaai Wa Lisani Minal Kadhibi Wa 'Aynee Minal Khiyanati Fa Innaka Ta'lamu Kha Inatal A'yuni Wa Ma Tukhfis Sudoor'. (Baihaqi)

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Shaykh Al-Albaani is of the view that both Ahadeeth are weak. He graded the first Hadeeth as weak in his study of Sunan At-Tirmidhi. The number of this Hadeeth in the collection of weak Ahadeeth of al-Jaami' as-Sagheer is 4097.

As for the second Hadeeth, its number is 1209.

Allah knows best.
