So we bid farewell to it (Ramadan) with the farewell of one whose parting pains us,
whose leaving fills us with gloom and loneliness, and to whom we have come to owe
a safeguarded claim, an observed inviolability, and a discharged right.
We say: Peace be upon thee, O greatest month of Allah! O festival of His friends!
(Imam Sajjad (AS) dua #45)

This month (Ramadan) stood among us in a standing place of praise, accompanied us with the companionship of one approved, and profited us with the most excellent profit of the world’s creatures. Then it parted from us at the completion of its time, the end of its term, and the fulfilment of its number. (Imam Sajjad (AS) dua #45)

… show vanity in praiseworthy habits such as the protection of the neighbour, the fulfilment of agreements, obedience to the virtuous, opposition to the haughty, extending generosity to others, abstention from rebellion, keeping aloof from blood-shed, doing justice to people, suppressing anger and avoiding trouble on the earth. (Imam Ali, sermon #191)

One who judges without disharmony and differences, his judgment is of the judgment of Allah, the Most Holy, the Most High. Whoever would judge in disharmonious manner with differences, and considers it as the rightful way of judging he has judged with the judgment of the shaytan. (Imam Jafer Sadeq (AS) Al Kafi, H 645, Ch. 41, h 3)

Glory be to Allah from Whom neither the blackness of dark dusk, or of gloomy night (falling) in the low parts of the earth or on high dim mountains is hidden. (Imam Ali (AS) sermon #181)
