The Beloved and Blessed Nabi صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has said: اُطْلُبُوا الْحَوَائِجَ اِلَی حِسَانِ الْوُجُوہ i.e. Seek [the fulfilment of] needs from the beautiful-faced ones. (Musannaf Ibn-e-Abi Shaybah, vol. 13, pp. 399, Hadees 26801)
Similarly, it is also stated in another Hadees, “اُطْلُبُوا الْحَوَائِجَ اِلَى حِسَانِ الْوُجُوہِ مَحَاسِنَ الْاَخْلَاق i.e. Seek [the fulfilment of] needs from the people who have beautiful faces [and] have good manners.”
The Arabic words “حِسَان الْوُجُوه” refer to the people whose faces are cheerful, lighting up with happiness. This is actually a proof that they are broad-chested [i.e. generous] and well-mannered and they have a wish to please people. The person who desires and wishes to please people is quick to fulfill their needs. He wants to please them by means of the happiness and cheerfulness of his face and seeks love from them. In fact, these beautiful-faced individuals get pleased by fulfilling the needs of others. Moreover, a well-mannered person feels shy if someone asking him for anything returns empty-handed from him. It is not difficult for a broad-chested person to help his brother. The one who is broad-chested is also open-handed. On the other hand, meanness is shown by a narrow-chested person. When any person asks him for anything, he feels fear that he himself needs it and will have to face poverty if he gives it to anyone else. Therefore, he keeps it for his own need.
This Hadees may also mean that if you present yourself in the court of the pious bondmen of Allah in such a state that you love them, express thanks to Allah عَزَّوَجَلَّ and adopt their habits and traits, i.e. you follow them, then Allah عَزَّوَجَلَّ will fulfil your needs. (Bahr-ul-Fawa`id, pp. 91 to 93)
Mentioned here is another meaning of this Hadees. Good faces mean that signs of happiness should appear from their faces when asked for anything. It is stated in another blessed Hadees, “Seek [the fulfillment of] your needs from beautiful-faced ones. If they fulfill needs, they will do with smiling faces.” (Faiz-ul-Qadeer, vol. 1, pp. 689, Taht-al-Hadees. 1107)
Ala Hadrat Imam Ahmad Raza Khan رَحْمَةُ اللهِ تَعَالٰی عَلَيْه stated: These good-faced individuals are blessed Awliya whom Husn-e-Azali (حسن ازلی) loves. (It is stated in a Hadees), “Allah عَزَّوَجَلَّ bestows such beauty as day-light upon the face of the one who offers Salah at night in abundance.” They are blessed with great generosity and munificence. Smiling face at the time of bestowment is a small fruit of it. (Fatawa Razawiyyah, vol. 30, pp. 391)
