إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ وَمَا أَدْرَاكَ مَا لَيْلَةُ الْقَدْرِ لَيْلَةُ الْقَدْرِ خَيْرٌ مِنْ أَلْفِ شَهْرٍ تَنَزَّلُ الْمَلَائِكَةُ وَالرُّوحُ فِيهَا بِإِذْنِ رَبِّهِمْ مِنْ كُلِّ أَمْرٍ سَلَامٌ هِيَ حَتَّىٰ مَطْلَعِ الْفَجْرِ
Indeed, We sent the Qur’an down during the Night of Decree. And what can make you know what is the Night of Decree? The Night of Decree is better than a thousand months. The angels and the Spirit descend therein by permission of their Lord for every matter. Peace it is until the emergence of dawn.
Surah Al Qadr

Hz. Talha ibn Ubayd ^Rz reported: Whenever the Messenger of Allah ^PBUH, saw the crescent moon, he would say:
اللَّهُمَّ أَهْلِلْهُ عَلَيْنَا بِالْيُمْنِ وَالْإِيمَانِ وَالسَّلَامَةِ وَالْإِسْلَامِ رَبِّي وَرَبُّكَ اللَّهُ
O Allah, bring it over us with blessings and faith, safety and Islam. My Lord and your Lord is Allah.

Hazrath Imam Mahdi al-Mauood ^PBUH held the skin of his body with two of his fingers and said that- “This flesh and skin is of this slave (of Allah), whoever rejects the Mahdi-ship (Mahdiat) of this person (zath) is a kafir.”

Ameer Ul Mumineen Hazrath Ali -ul Murtuza ^Rz. is narrated to have said that: “Be not friend with a fool, for he will harm you while meaning to do good to you.”
