وَهُمْ رَبِيعٌ لِلْمُجَاوِرِ فِيهِمُ وَالْمُرْمِلَاتِ إِذَا تَطَاوَلَ عَامُهَا
They are like springtime for a stranger living among them and for impoverished women when their year of hardship drags on.
Rabīʿ is metaphorical spring: renewal, growth and relief. Al-murmilāt denotes women with little or no means, and taṭāwala ʿāmuhā makes a year of hardship feel extended.
The poet presents hospitality toward strangers and support for the vulnerable as evidence of communal distinction. Help is compared to the life-giving effect of spring.
